Given numbers are 863, 895, 744, 644

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

Apply this formula for all numbers.

Step1:

LCM(863, 895) = 772385

GCD(863, 895) = ( 863 x 895 ) / 772385

= 863 / 895

= 863

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 863, 895, 744, 644 is 1
