GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 987) = 30597
GCD(651, 987) = ( 651 x 987 ) / 30597
= 651 / 987
= 651
Step2:
LCM(21, 351) = 2457
GCD(21, 351) = ( 21 x 351 ) / 2457
= 21 / 351
= 21
Step3:
LCM(3, 378) = 378
GCD(3, 378) = ( 3 x 378 ) / 378
= 3 / 378
= 3
So, Greatest Common Divisor of 651, 987, 351, 378 is 3
