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

Apply this formula for all numbers.

Step1:

LCM(455, 784) = 50960

GCD(455, 784) = ( 455 x 784 ) / 50960

= 455 / 784

= 455

Step2:

LCM(7, 140) = 140

GCD(7, 140) = ( 7 x 140 ) / 140

= 7 / 140

= 7

So, Greatest Common Divisor of 455, 784, 140 is 7
