Given numbers are 909, 966, 780, 970
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 966) = 292698
GCD(909, 966) = ( 909 x 966 ) / 292698
= 909 / 966
= 909
Step2:
LCM(3, 780) = 780
GCD(3, 780) = ( 3 x 780 ) / 780
= 3 / 780
= 3
Step3:
LCM(3, 970) = 2910
GCD(3, 970) = ( 3 x 970 ) / 2910
= 3 / 970
= 3
So, Greatest Common Divisor of 909, 966, 780, 970 is 1
