Given numbers are 741, 361, 765, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(741, 361) = 14079
GCD(741, 361) = ( 741 x 361 ) / 14079
= 741 / 361
= 741
Step2:
LCM(19, 765) = 14535
GCD(19, 765) = ( 19 x 765 ) / 14535
= 19 / 765
= 19
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 741, 361, 765, 638 is 1
