Given numbers are 220, 128, 86, 718

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

Apply this formula for all numbers.

Step1:

LCM(220, 128) = 7040

GCD(220, 128) = ( 220 x 128 ) / 7040

= 220 / 128

= 220

Step2:

LCM(4, 86) = 172

GCD(4, 86) = ( 4 x 86 ) / 172

= 4 / 86

= 4

Step3:

LCM(2, 718) = 718

GCD(2, 718) = ( 2 x 718 ) / 718

= 2 / 718

= 2

So, Greatest Common Divisor of 220, 128, 86, 718 is 2
