Given numbers are 895, 870, 491, 645

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

Apply this formula for all numbers.

Step1:

LCM(895, 870) = 155730

GCD(895, 870) = ( 895 x 870 ) / 155730

= 895 / 870

= 895

Step2:

LCM(5, 491) = 2455

GCD(5, 491) = ( 5 x 491 ) / 2455

= 5 / 491

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 895, 870, 491, 645 is 1
