Given numbers are 920, 270, 644, 486

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

Apply this formula for all numbers.

Step1:

LCM(920, 270) = 24840

GCD(920, 270) = ( 920 x 270 ) / 24840

= 920 / 270

= 920

Step2:

LCM(10, 644) = 3220

GCD(10, 644) = ( 10 x 644 ) / 3220

= 10 / 644

= 10

Step3:

LCM(2, 486) = 486

GCD(2, 486) = ( 2 x 486 ) / 486

= 2 / 486

= 2

So, Greatest Common Divisor of 920, 270, 644, 486 is 2
