Given numbers are 641, 978, 573, 871

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

Apply this formula for all numbers.

Step1:

LCM(641, 978) = 626898

GCD(641, 978) = ( 641 x 978 ) / 626898

= 641 / 978

= 641

Step2:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 641, 978, 573, 871 is 1
