LONDON (Reuters) - Following is a summary of British Queen Elizabeth's life in numbers:
* Queen Elizabeth II was the 40th monarch in England since Norman King William the Conqueror obtained the crown. Her reign of 70 years, 7 months and 2 days was the longest in the history of what became the United Kingdom. During that time she has given her assent to more than 4,000 Acts of Parliament.
* Elizabeth visited well over 100 countries during her reign. In 2016, Buckingham Palace said she had travelled at least 1,032,513 miles (1,661,668 km) to 117 nations. She paid the most visits to Canada.
* She had 15 prime ministers, starting with Winston Churchill through to Liz Truss. During her reign there were 14 U.S. presidents and seven popes.
* She had four children, eight grandchildren, and 12 great-grandchildren.
* She sent more than 300,000 congratulatory cards to people celebrating their 100th birthdays, and more than 900,000 messages to couples marking their Diamond (60th) Wedding Anniversaries.
* She loved dogs and owned more than 30 Corgis and Dorgis during her reign, most of which have been descended from her first Corgi, Susan, which was given to Elizabeth when she turned 18 in 1944.
