Given numbers are 645, 506, 591, 912
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 506) = 326370
GCD(645, 506) = ( 645 x 506 ) / 326370
= 645 / 506
= 645
Step2:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
Step3:
LCM(1, 912) = 912
GCD(1, 912) = ( 1 x 912 ) / 912
= 1 / 912
= 1
So, Greatest Common Divisor of 645, 506, 591, 912 is 1
