Given numbers are 630, 690, 639, 372
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 690) = 14490
GCD(630, 690) = ( 630 x 690 ) / 14490
= 630 / 690
= 630
Step2:
LCM(30, 639) = 6390
GCD(30, 639) = ( 30 x 639 ) / 6390
= 30 / 639
= 30
Step3:
LCM(3, 372) = 372
GCD(3, 372) = ( 3 x 372 ) / 372
= 3 / 372
= 3
So, Greatest Common Divisor of 630, 690, 639, 372 is 3
