Given numbers are 861, 661, 714, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 661) = 569121
GCD(861, 661) = ( 861 x 661 ) / 569121
= 861 / 661
= 861
Step2:
LCM(1, 714) = 714
GCD(1, 714) = ( 1 x 714 ) / 714
= 1 / 714
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 861, 661, 714, 865 is 1
