Given numbers are 765, 654, 628, 998
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 654) = 166770
GCD(765, 654) = ( 765 x 654 ) / 166770
= 765 / 654
= 765
Step2:
LCM(3, 628) = 1884
GCD(3, 628) = ( 3 x 628 ) / 1884
= 3 / 628
= 3
Step3:
LCM(1, 998) = 998
GCD(1, 998) = ( 1 x 998 ) / 998
= 1 / 998
= 1
So, Greatest Common Divisor of 765, 654, 628, 998 is 1
