Given numbers are 215, 430, 172, 902

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

Apply this formula for all numbers.

Step1:

LCM(215, 430) = 430

GCD(215, 430) = ( 215 x 430 ) / 430

= 215 / 430

= 215

Step2:

LCM(215, 172) = 860

GCD(215, 172) = ( 215 x 172 ) / 860

= 215 / 172

= 215

Step3:

LCM(43, 902) = 38786

GCD(43, 902) = ( 43 x 902 ) / 38786

= 43 / 902

= 43

So, Greatest Common Divisor of 215, 430, 172, 902 is 1
