Given numbers are 886, 644, 430, 830

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

Apply this formula for all numbers.

Step1:

LCM(886, 644) = 285292

GCD(886, 644) = ( 886 x 644 ) / 285292

= 886 / 644

= 886

Step2:

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

= 2 / 430

= 2

Step3:

LCM(2, 830) = 830

GCD(2, 830) = ( 2 x 830 ) / 830

= 2 / 830

= 2

So, Greatest Common Divisor of 886, 644, 430, 830 is 2
