Given numbers are 270, 906, 724, 644

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

Apply this formula for all numbers.

Step1:

LCM(270, 906) = 40770

GCD(270, 906) = ( 270 x 906 ) / 40770

= 270 / 906

= 270

Step2:

LCM(6, 724) = 2172

GCD(6, 724) = ( 6 x 724 ) / 2172

= 6 / 724

= 6

Step3:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

So, Greatest Common Divisor of 270, 906, 724, 644 is 2
