Given numbers are 708, 387, 15, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(708, 387) = 91332
GCD(708, 387) = ( 708 x 387 ) / 91332
= 708 / 387
= 708
Step2:
LCM(3, 15) = 15
GCD(3, 15) = ( 3 x 15 ) / 15
= 3 / 15
= 3
Step3:
LCM(3, 660) = 660
GCD(3, 660) = ( 3 x 660 ) / 660
= 3 / 660
= 3
So, Greatest Common Divisor of 708, 387, 15, 660 is 3
