GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 820) = 614180
GCD(749, 820) = ( 749 x 820 ) / 614180
= 749 / 820
= 749
Step2:
LCM(1, 567) = 567
GCD(1, 567) = ( 1 x 567 ) / 567
= 1 / 567
= 1
Step3:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
So, Greatest Common Divisor of 749, 820, 567, 656 is 1
