Given numbers are 111, 138, 157, 784

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

Apply this formula for all numbers.

Step1:

LCM(111, 138) = 5106

GCD(111, 138) = ( 111 x 138 ) / 5106

= 111 / 138

= 111

Step2:

LCM(3, 157) = 471

GCD(3, 157) = ( 3 x 157 ) / 471

= 3 / 157

= 3

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 111, 138, 157, 784 is 1
