Given numbers are 989, 874, 523, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 874) = 37582
GCD(989, 874) = ( 989 x 874 ) / 37582
= 989 / 874
= 989
Step2:
LCM(23, 523) = 12029
GCD(23, 523) = ( 23 x 523 ) / 12029
= 23 / 523
= 23
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 989, 874, 523, 154 is 1
