Given numbers are 645, 287, 60, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 287) = 185115
GCD(645, 287) = ( 645 x 287 ) / 185115
= 645 / 287
= 645
Step2:
LCM(1, 60) = 60
GCD(1, 60) = ( 1 x 60 ) / 60
= 1 / 60
= 1
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 645, 287, 60, 126 is 1
