Given numbers are 784, 203, 605, 157

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

Apply this formula for all numbers.

Step1:

LCM(784, 203) = 22736

GCD(784, 203) = ( 784 x 203 ) / 22736

= 784 / 203

= 784

Step2:

LCM(7, 605) = 4235

GCD(7, 605) = ( 7 x 605 ) / 4235

= 7 / 605

= 7

Step3:

LCM(1, 157) = 157

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

= 1 / 157

= 1

So, Greatest Common Divisor of 784, 203, 605, 157 is 1
