Given numbers are 573, 645, 721, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(573, 645) = 123195
GCD(573, 645) = ( 573 x 645 ) / 123195
= 573 / 645
= 573
Step2:
LCM(3, 721) = 2163
GCD(3, 721) = ( 3 x 721 ) / 2163
= 3 / 721
= 3
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 573, 645, 721, 611 is 1
