Given numbers are 646, 497, 410, 126

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

Apply this formula for all numbers.

Step1:

LCM(646, 497) = 321062

GCD(646, 497) = ( 646 x 497 ) / 321062

= 646 / 497

= 646

Step2:

LCM(1, 410) = 410

GCD(1, 410) = ( 1 x 410 ) / 410

= 1 / 410

= 1

Step3:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

So, Greatest Common Divisor of 646, 497, 410, 126 is 1
