Given numbers are 784, 392, 156, 135

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

Apply this formula for all numbers.

Step1:

LCM(784, 392) = 784

GCD(784, 392) = ( 784 x 392 ) / 784

= 784 / 392

= 784

Step2:

LCM(392, 156) = 15288

GCD(392, 156) = ( 392 x 156 ) / 15288

= 392 / 156

= 392

Step3:

LCM(4, 135) = 540

GCD(4, 135) = ( 4 x 135 ) / 540

= 4 / 135

= 4

So, Greatest Common Divisor of 784, 392, 156, 135 is 1
