Given numbers are 646, 785, 35, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 785) = 507110
GCD(646, 785) = ( 646 x 785 ) / 507110
= 646 / 785
= 646
Step2:
LCM(1, 35) = 35
GCD(1, 35) = ( 1 x 35 ) / 35
= 1 / 35
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 646, 785, 35, 809 is 1
