GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 516) = 1548
GCD(387, 516) = ( 387 x 516 ) / 1548
= 387 / 516
= 387
Step2:
LCM(129, 865) = 111585
GCD(129, 865) = ( 129 x 865 ) / 111585
= 129 / 865
= 129
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 387, 516, 865, 855 is 1
