Given numbers are 153, 921, 784, 812

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

Apply this formula for all numbers.

Step1:

LCM(153, 921) = 46971

GCD(153, 921) = ( 153 x 921 ) / 46971

= 153 / 921

= 153

Step2:

LCM(3, 784) = 2352

GCD(3, 784) = ( 3 x 784 ) / 2352

= 3 / 784

= 3

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 153, 921, 784, 812 is 1
