Given numbers are 620, 155, 227, 570

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

Apply this formula for all numbers.

Step1:

LCM(620, 155) = 620

GCD(620, 155) = ( 620 x 155 ) / 620

= 620 / 155

= 620

Step2:

LCM(155, 227) = 35185

GCD(155, 227) = ( 155 x 227 ) / 35185

= 155 / 227

= 155

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 620, 155, 227, 570 is 1
