Given numbers are 646, 452, 127, 312

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

Apply this formula for all numbers.

Step1:

LCM(646, 452) = 145996

GCD(646, 452) = ( 646 x 452 ) / 145996

= 646 / 452

= 646

Step2:

LCM(2, 127) = 254

GCD(2, 127) = ( 2 x 127 ) / 254

= 2 / 127

= 2

Step3:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

So, Greatest Common Divisor of 646, 452, 127, 312 is 1
