Given numbers are 427, 980, 965, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 980) = 59780
GCD(427, 980) = ( 427 x 980 ) / 59780
= 427 / 980
= 427
Step2:
LCM(7, 965) = 6755
GCD(7, 965) = ( 7 x 965 ) / 6755
= 7 / 965
= 7
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 427, 980, 965, 678 is 1
