GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(697, 668) = 465596
GCD(697, 668) = ( 697 x 668 ) / 465596
= 697 / 668
= 697
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 697, 668, 453, 891 is 1
