Given numbers are 438, 628, 158, 895

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

Apply this formula for all numbers.

Step1:

LCM(438, 628) = 137532

GCD(438, 628) = ( 438 x 628 ) / 137532

= 438 / 628

= 438

Step2:

LCM(2, 158) = 158

GCD(2, 158) = ( 2 x 158 ) / 158

= 2 / 158

= 2

Step3:

LCM(2, 895) = 1790

GCD(2, 895) = ( 2 x 895 ) / 1790

= 2 / 895

= 2

So, Greatest Common Divisor of 438, 628, 158, 895 is 1
