Given numbers are 413, 645, 252, 688
The list of prime factors of all numbers are
Prime factors of 413 are 7 x 59
Prime factors of 645 are 3 x 5 x 43
Prime factors of 252 are 2 x 2 x 3 x 3 x 7
Prime factors of 688 are 2 x 2 x 2 x 2 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 413, 645, 252, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(413, 645) = 266385
GCD(413, 645) = ( 413 x 645 ) / 266385
= 413 / 645
= 413
Step2:
LCM(1, 252) = 252
GCD(1, 252) = ( 1 x 252 ) / 252
= 1 / 252
= 1
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 413, 645, 252, 688 is 1
