GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 153) = 97614
GCD(638, 153) = ( 638 x 153 ) / 97614
= 638 / 153
= 638
Step2:
LCM(1, 889) = 889
GCD(1, 889) = ( 1 x 889 ) / 889
= 1 / 889
= 1
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 638, 153, 889, 763 is 1
