Given numbers are 561, 757, 290

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

Apply this formula for all numbers.

Step1:

LCM(561, 757) = 424677

GCD(561, 757) = ( 561 x 757 ) / 424677

= 561 / 757

= 561

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 561, 757, 290 is 1
