Given numbers are 643, 367, 695, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 367) = 235981
GCD(643, 367) = ( 643 x 367 ) / 235981
= 643 / 367
= 643
Step2:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 643, 367, 695, 785 is 1
