Given numbers are 989, 397, 987, 453
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 397) = 392633
GCD(989, 397) = ( 989 x 397 ) / 392633
= 989 / 397
= 989
Step2:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
Step3:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
So, Greatest Common Divisor of 989, 397, 987, 453 is 1
