Given numbers are 220, 686, 570, 146

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

Apply this formula for all numbers.

Step1:

LCM(220, 686) = 75460

GCD(220, 686) = ( 220 x 686 ) / 75460

= 220 / 686

= 220

Step2:

LCM(2, 570) = 570

GCD(2, 570) = ( 2 x 570 ) / 570

= 2 / 570

= 2

Step3:

LCM(2, 146) = 146

GCD(2, 146) = ( 2 x 146 ) / 146

= 2 / 146

= 2

So, Greatest Common Divisor of 220, 686, 570, 146 is 2
