Given numbers are 646, 782, 742, 954

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

Apply this formula for all numbers.

Step1:

LCM(646, 782) = 14858

GCD(646, 782) = ( 646 x 782 ) / 14858

= 646 / 782

= 646

Step2:

LCM(34, 742) = 12614

GCD(34, 742) = ( 34 x 742 ) / 12614

= 34 / 742

= 34

Step3:

LCM(2, 954) = 954

GCD(2, 954) = ( 2 x 954 ) / 954

= 2 / 954

= 2

So, Greatest Common Divisor of 646, 782, 742, 954 is 2
