Given numbers are 812, 784, 419, 861

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

Apply this formula for all numbers.

Step1:

LCM(812, 784) = 22736

GCD(812, 784) = ( 812 x 784 ) / 22736

= 812 / 784

= 812

Step2:

LCM(28, 419) = 11732

GCD(28, 419) = ( 28 x 419 ) / 11732

= 28 / 419

= 28

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 812, 784, 419, 861 is 1
