Prime factors of 790 are 2 x 5 x 79
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 640, 554, 433, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 554) = 177280
GCD(640, 554) = ( 640 x 554 ) / 177280
= 640 / 554
= 640
Step2:
LCM(2, 433) = 866
GCD(2, 433) = ( 2 x 433 ) / 866
= 2 / 433
= 2
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 640, 554, 433, 790 is 1
