Given numbers are 409, 404, 645, 607
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 404) = 165236
GCD(409, 404) = ( 409 x 404 ) / 165236
= 409 / 404
= 409
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 607) = 607
GCD(1, 607) = ( 1 x 607 ) / 607
= 1 / 607
= 1
So, Greatest Common Divisor of 409, 404, 645, 607 is 1
