Given numbers are 930, 126, 964, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(930, 126) = 19530
GCD(930, 126) = ( 930 x 126 ) / 19530
= 930 / 126
= 930
Step2:
LCM(6, 964) = 2892
GCD(6, 964) = ( 6 x 964 ) / 2892
= 6 / 964
= 6
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 930, 126, 964, 639 is 1
