GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 779) = 401185
GCD(515, 779) = ( 515 x 779 ) / 401185
= 515 / 779
= 515
Step2:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
Step3:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
So, Greatest Common Divisor of 515, 779, 715, 387 is 1
