Given numbers are 643, 861, 950, 135

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

Apply this formula for all numbers.

Step1:

LCM(643, 861) = 553623

GCD(643, 861) = ( 643 x 861 ) / 553623

= 643 / 861

= 643

Step2:

LCM(1, 950) = 950

GCD(1, 950) = ( 1 x 950 ) / 950

= 1 / 950

= 1

Step3:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

So, Greatest Common Divisor of 643, 861, 950, 135 is 1
