Given numbers are 949, 915, 643, 931

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

Apply this formula for all numbers.

Step1:

LCM(949, 915) = 868335

GCD(949, 915) = ( 949 x 915 ) / 868335

= 949 / 915

= 949

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 949, 915, 643, 931 is 1
