Given numbers are 643, 695, 588, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 695) = 446885
GCD(643, 695) = ( 643 x 695 ) / 446885
= 643 / 695
= 643
Step2:
LCM(1, 588) = 588
GCD(1, 588) = ( 1 x 588 ) / 588
= 1 / 588
= 1
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 643, 695, 588, 355 is 1
