Given numbers are 771, 210, 593, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 210) = 53970
GCD(771, 210) = ( 771 x 210 ) / 53970
= 771 / 210
= 771
Step2:
LCM(3, 593) = 1779
GCD(3, 593) = ( 3 x 593 ) / 1779
= 3 / 593
= 3
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 771, 210, 593, 647 is 1
