GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 987) = 301035
GCD(915, 987) = ( 915 x 987 ) / 301035
= 915 / 987
= 915
Step2:
LCM(3, 534) = 534
GCD(3, 534) = ( 3 x 534 ) / 534
= 3 / 534
= 3
Step3:
LCM(3, 621) = 621
GCD(3, 621) = ( 3 x 621 ) / 621
= 3 / 621
= 3
So, Greatest Common Divisor of 915, 987, 534, 621 is 3
