Given numbers are 778, 180, 970, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 180) = 70020
GCD(778, 180) = ( 778 x 180 ) / 70020
= 778 / 180
= 778
Step2:
LCM(2, 970) = 970
GCD(2, 970) = ( 2 x 970 ) / 970
= 2 / 970
= 2
Step3:
LCM(2, 409) = 818
GCD(2, 409) = ( 2 x 409 ) / 818
= 2 / 409
= 2
So, Greatest Common Divisor of 778, 180, 970, 409 is 1
