Given numbers are 747, 409, 605, 730
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 409) = 305523
GCD(747, 409) = ( 747 x 409 ) / 305523
= 747 / 409
= 747
Step2:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
Step3:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
So, Greatest Common Divisor of 747, 409, 605, 730 is 1
