Given numbers are 124, 897, 445, 220

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

Apply this formula for all numbers.

Step1:

LCM(124, 897) = 111228

GCD(124, 897) = ( 124 x 897 ) / 111228

= 124 / 897

= 124

Step2:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 124, 897, 445, 220 is 1
