Given numbers are 644, 866, 848, 635

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

Apply this formula for all numbers.

Step1:

LCM(644, 866) = 278852

GCD(644, 866) = ( 644 x 866 ) / 278852

= 644 / 866

= 644

Step2:

LCM(2, 848) = 848

GCD(2, 848) = ( 2 x 848 ) / 848

= 2 / 848

= 2

Step3:

LCM(2, 635) = 1270

GCD(2, 635) = ( 2 x 635 ) / 1270

= 2 / 635

= 2

So, Greatest Common Divisor of 644, 866, 848, 635 is 1
