GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(784, 152) = 14896

GCD(784, 152) = ( 784 x 152 ) / 14896

= 784 / 152

= 784

Step2:

LCM(8, 878) = 3512

GCD(8, 878) = ( 8 x 878 ) / 3512

= 8 / 878

= 8

Step3:

LCM(2, 156) = 156

GCD(2, 156) = ( 2 x 156 ) / 156

= 2 / 156

= 2

So, Greatest Common Divisor of 784, 152, 878, 156 is 2
