Given numbers are 644, 268, 965, 898

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

Apply this formula for all numbers.

Step1:

LCM(644, 268) = 43148

GCD(644, 268) = ( 644 x 268 ) / 43148

= 644 / 268

= 644

Step2:

LCM(4, 965) = 3860

GCD(4, 965) = ( 4 x 965 ) / 3860

= 4 / 965

= 4

Step3:

LCM(1, 898) = 898

GCD(1, 898) = ( 1 x 898 ) / 898

= 1 / 898

= 1

So, Greatest Common Divisor of 644, 268, 965, 898 is 1
