Given numbers are 647, 433, 79, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 433) = 280151
GCD(647, 433) = ( 647 x 433 ) / 280151
= 647 / 433
= 647
Step2:
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
= 1 / 79
= 1
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 647, 433, 79, 321 is 1
