Given numbers are 785, 637, 506, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 637) = 500045
GCD(785, 637) = ( 785 x 637 ) / 500045
= 785 / 637
= 785
Step2:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 785, 637, 506, 409 is 1
