Given numbers are 771, 442, 897, 653
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 442) = 340782
GCD(771, 442) = ( 771 x 442 ) / 340782
= 771 / 442
= 771
Step2:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
Step3:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
So, Greatest Common Divisor of 771, 442, 897, 653 is 1
