Given numbers are 645, 586, 464, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 586) = 377970
GCD(645, 586) = ( 645 x 586 ) / 377970
= 645 / 586
= 645
Step2:
LCM(1, 464) = 464
GCD(1, 464) = ( 1 x 464 ) / 464
= 1 / 464
= 1
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 645, 586, 464, 628 is 1
