Given numbers are 646, 142, 181, 468

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

Apply this formula for all numbers.

Step1:

LCM(646, 142) = 45866

GCD(646, 142) = ( 646 x 142 ) / 45866

= 646 / 142

= 646

Step2:

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

= 2 / 181

= 2

Step3:

LCM(1, 468) = 468

GCD(1, 468) = ( 1 x 468 ) / 468

= 1 / 468

= 1

So, Greatest Common Divisor of 646, 142, 181, 468 is 1
