Given numbers are 561, 542, 76, 719

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

Apply this formula for all numbers.

Step1:

LCM(561, 542) = 304062

GCD(561, 542) = ( 561 x 542 ) / 304062

= 561 / 542

= 561

Step2:

LCM(1, 76) = 76

GCD(1, 76) = ( 1 x 76 ) / 76

= 1 / 76

= 1

Step3:

LCM(1, 719) = 719

GCD(1, 719) = ( 1 x 719 ) / 719

= 1 / 719

= 1

So, Greatest Common Divisor of 561, 542, 76, 719 is 1
