Given numbers are 899, 638, 817, 215

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

Apply this formula for all numbers.

Step1:

LCM(899, 638) = 19778

GCD(899, 638) = ( 899 x 638 ) / 19778

= 899 / 638

= 899

Step2:

LCM(29, 817) = 23693

GCD(29, 817) = ( 29 x 817 ) / 23693

= 29 / 817

= 29

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 899, 638, 817, 215 is 1
