GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 891) = 576477
GCD(647, 891) = ( 647 x 891 ) / 576477
= 647 / 891
= 647
Step2:
LCM(1, 592) = 592
GCD(1, 592) = ( 1 x 592 ) / 592
= 1 / 592
= 1
Step3:
LCM(1, 988) = 988
GCD(1, 988) = ( 1 x 988 ) / 988
= 1 / 988
= 1
So, Greatest Common Divisor of 647, 891, 592, 988 is 1
