Given numbers are 145, 220, 637, 159

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

Apply this formula for all numbers.

Step1:

LCM(145, 220) = 6380

GCD(145, 220) = ( 145 x 220 ) / 6380

= 145 / 220

= 145

Step2:

LCM(5, 637) = 3185

GCD(5, 637) = ( 5 x 637 ) / 3185

= 5 / 637

= 5

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 145, 220, 637, 159 is 1
