Given numbers are 784, 147, 15, 610

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

Apply this formula for all numbers.

Step1:

LCM(784, 147) = 2352

GCD(784, 147) = ( 784 x 147 ) / 2352

= 784 / 147

= 784

Step2:

LCM(49, 15) = 735

GCD(49, 15) = ( 49 x 15 ) / 735

= 49 / 15

= 49

Step3:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

So, Greatest Common Divisor of 784, 147, 15, 610 is 1
