Given numbers are 138, 616, 181, 784

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

Prime factors of 181 are 181

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 138, 616, 181, 784

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

Apply this formula for all numbers.

Step1:

LCM(138, 616) = 42504

GCD(138, 616) = ( 138 x 616 ) / 42504

= 138 / 616

= 138

Step2:

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

= 2 / 181

= 2

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 138, 616, 181, 784 is 1
