Given numbers are 621, 714, 168, 540
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 714) = 147798
GCD(621, 714) = ( 621 x 714 ) / 147798
= 621 / 714
= 621
Step2:
LCM(3, 168) = 168
GCD(3, 168) = ( 3 x 168 ) / 168
= 3 / 168
= 3
Step3:
LCM(3, 540) = 540
GCD(3, 540) = ( 3 x 540 ) / 540
= 3 / 540
= 3
So, Greatest Common Divisor of 621, 714, 168, 540 is 3
