Given numbers are 643, 609, 870, 718

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(643, 609) = 391587

GCD(643, 609) = ( 643 x 609 ) / 391587

= 643 / 609

= 643

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 643, 609, 870, 718 is 1
