Given numbers are 145, 958, 20, 552

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

Apply this formula for all numbers.

Step1:

LCM(145, 958) = 138910

GCD(145, 958) = ( 145 x 958 ) / 138910

= 145 / 958

= 145

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 552) = 552

GCD(1, 552) = ( 1 x 552 ) / 552

= 1 / 552

= 1

So, Greatest Common Divisor of 145, 958, 20, 552 is 1
