Given numbers are 784, 491, 157, 125

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

Apply this formula for all numbers.

Step1:

LCM(784, 491) = 384944

GCD(784, 491) = ( 784 x 491 ) / 384944

= 784 / 491

= 784

Step2:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

Step3:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

So, Greatest Common Divisor of 784, 491, 157, 125 is 1
