Given numbers are 100, 640, 217, 676
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 217 are 7 x 31
Prime factors of 676 are 2 x 2 x 13 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 640, 217, 676
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 640) = 3200
GCD(100, 640) = ( 100 x 640 ) / 3200
= 100 / 640
= 100
Step2:
LCM(20, 217) = 4340
GCD(20, 217) = ( 20 x 217 ) / 4340
= 20 / 217
= 20
Step3:
LCM(1, 676) = 676
GCD(1, 676) = ( 1 x 676 ) / 676
= 1 / 676
= 1
So, Greatest Common Divisor of 100, 640, 217, 676 is 1
