GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 858) = 110682
GCD(387, 858) = ( 387 x 858 ) / 110682
= 387 / 858
= 387
Step2:
LCM(3, 791) = 2373
GCD(3, 791) = ( 3 x 791 ) / 2373
= 3 / 791
= 3
Step3:
LCM(1, 560) = 560
GCD(1, 560) = ( 1 x 560 ) / 560
= 1 / 560
= 1
So, Greatest Common Divisor of 387, 858, 791, 560 is 1
