Given numbers are 789, 441, 989, 635
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 441) = 115983
GCD(789, 441) = ( 789 x 441 ) / 115983
= 789 / 441
= 789
Step2:
LCM(3, 989) = 2967
GCD(3, 989) = ( 3 x 989 ) / 2967
= 3 / 989
= 3
Step3:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
So, Greatest Common Divisor of 789, 441, 989, 635 is 1
