Given numbers are 644, 920, 490, 593

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

Apply this formula for all numbers.

Step1:

LCM(644, 920) = 6440

GCD(644, 920) = ( 644 x 920 ) / 6440

= 644 / 920

= 644

Step2:

LCM(92, 490) = 22540

GCD(92, 490) = ( 92 x 490 ) / 22540

= 92 / 490

= 92

Step3:

LCM(2, 593) = 1186

GCD(2, 593) = ( 2 x 593 ) / 1186

= 2 / 593

= 2

So, Greatest Common Divisor of 644, 920, 490, 593 is 1
