Given numbers are 181, 131, 953, 646

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

Apply this formula for all numbers.

Step1:

LCM(181, 131) = 23711

GCD(181, 131) = ( 181 x 131 ) / 23711

= 181 / 131

= 181

Step2:

LCM(1, 953) = 953

GCD(1, 953) = ( 1 x 953 ) / 953

= 1 / 953

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 181, 131, 953, 646 is 1
