Given numbers are 645, 939, 418, 106
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 939) = 201885
GCD(645, 939) = ( 645 x 939 ) / 201885
= 645 / 939
= 645
Step2:
LCM(3, 418) = 1254
GCD(3, 418) = ( 3 x 418 ) / 1254
= 3 / 418
= 3
Step3:
LCM(1, 106) = 106
GCD(1, 106) = ( 1 x 106 ) / 106
= 1 / 106
= 1
So, Greatest Common Divisor of 645, 939, 418, 106 is 1
