Given numbers are 646, 871, 90

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

Apply this formula for all numbers.

Step1:

LCM(646, 871) = 562666

GCD(646, 871) = ( 646 x 871 ) / 562666

= 646 / 871

= 646

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

So, Greatest Common Divisor of 646, 871, 90 is 1
