Given numbers are 870, 347, 989, 641

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

Apply this formula for all numbers.

Step1:

LCM(870, 347) = 301890

GCD(870, 347) = ( 870 x 347 ) / 301890

= 870 / 347

= 870

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 870, 347, 989, 641 is 1
