Given numbers are 964, 456, 391, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(964, 456) = 109896
GCD(964, 456) = ( 964 x 456 ) / 109896
= 964 / 456
= 964
Step2:
LCM(4, 391) = 1564
GCD(4, 391) = ( 4 x 391 ) / 1564
= 4 / 391
= 4
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 964, 456, 391, 124 is 1
