GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 774) = 54954
GCD(142, 774) = ( 142 x 774 ) / 54954
= 142 / 774
= 142
Step2:
LCM(2, 931) = 1862
GCD(2, 931) = ( 2 x 931 ) / 1862
= 2 / 931
= 2
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 142, 774, 931, 865 is 1
