Given numbers are 986, 977, 957, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(986, 977) = 963322
GCD(986, 977) = ( 986 x 977 ) / 963322
= 986 / 977
= 986
Step2:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 986, 977, 957, 489 is 1
