Given numbers are 274, 487, 644

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

Apply this formula for all numbers.

Step1:

LCM(274, 487) = 133438

GCD(274, 487) = ( 274 x 487 ) / 133438

= 274 / 487

= 274

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 274, 487, 644 is 1
