Given numbers are 100, 249, 490, 651
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 249 are 3 x 83
Prime factors of 490 are 2 x 5 x 7 x 7
Prime factors of 651 are 3 x 7 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 249, 490, 651
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 249) = 24900
GCD(100, 249) = ( 100 x 249 ) / 24900
= 100 / 249
= 100
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
So, Greatest Common Divisor of 100, 249, 490, 651 is 1
