Calculating
100 factorial, written as 100!, means multiplying all the whole numbers from 1 to 100 together. It's a very big number:
100! = 1 x 2 x 3 x 4 x 5 x ... x 98 x 99 x 100
This number is so large that it has 24 zeros at the end! So, 100! is:
100! = 93,326,215,443,944,152,681,699,238,856,266,700,490,715,968,264,381,621,468,592,963,895,217,599,993,229,915,608,941,463,976,156,518,286,253,697,920,827,223,758,251,185,210,916,864,000,000,000,000,000
