Given numbers are 645, 741, 797, 565
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 741) = 159315
GCD(645, 741) = ( 645 x 741 ) / 159315
= 645 / 741
= 645
Step2:
LCM(3, 797) = 2391
GCD(3, 797) = ( 3 x 797 ) / 2391
= 3 / 797
= 3
Step3:
LCM(1, 565) = 565
GCD(1, 565) = ( 1 x 565 ) / 565
= 1 / 565
= 1
So, Greatest Common Divisor of 645, 741, 797, 565 is 1
