Given numbers are 771, 906, 420, 949
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 906) = 232842
GCD(771, 906) = ( 771 x 906 ) / 232842
= 771 / 906
= 771
Step2:
LCM(3, 420) = 420
GCD(3, 420) = ( 3 x 420 ) / 420
= 3 / 420
= 3
Step3:
LCM(3, 949) = 2847
GCD(3, 949) = ( 3 x 949 ) / 2847
= 3 / 949
= 3
So, Greatest Common Divisor of 771, 906, 420, 949 is 1
