Given numbers are 420, 734, 451, 917
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 734 are 2 x 367
Prime factors of 451 are 11 x 41
Prime factors of 917 are 7 x 131
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 734, 451, 917
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 734) = 154140
GCD(420, 734) = ( 420 x 734 ) / 154140
= 420 / 734
= 420
Step2:
LCM(2, 451) = 902
GCD(2, 451) = ( 2 x 451 ) / 902
= 2 / 451
= 2
Step3:
LCM(1, 917) = 917
GCD(1, 917) = ( 1 x 917 ) / 917
= 1 / 917
= 1
So, Greatest Common Divisor of 420, 734, 451, 917 is 1
