Given numbers are 729, 147, 921, 862

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

Apply this formula for all numbers.

Step1:

LCM(729, 147) = 35721

GCD(729, 147) = ( 729 x 147 ) / 35721

= 729 / 147

= 729

Step2:

LCM(3, 921) = 921

GCD(3, 921) = ( 3 x 921 ) / 921

= 3 / 921

= 3

Step3:

LCM(3, 862) = 2586

GCD(3, 862) = ( 3 x 862 ) / 2586

= 3 / 862

= 3

So, Greatest Common Divisor of 729, 147, 921, 862 is 1
