Given numbers are 641, 561, 491, 332

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

Apply this formula for all numbers.

Step1:

LCM(641, 561) = 359601

GCD(641, 561) = ( 641 x 561 ) / 359601

= 641 / 561

= 641

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

So, Greatest Common Divisor of 641, 561, 491, 332 is 1
