Given numbers are 147, 721, 497, 531

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

Apply this formula for all numbers.

Step1:

LCM(147, 721) = 15141

GCD(147, 721) = ( 147 x 721 ) / 15141

= 147 / 721

= 147

Step2:

LCM(7, 497) = 497

GCD(7, 497) = ( 7 x 497 ) / 497

= 7 / 497

= 7

Step3:

LCM(7, 531) = 3717

GCD(7, 531) = ( 7 x 531 ) / 3717

= 7 / 531

= 7

So, Greatest Common Divisor of 147, 721, 497, 531 is 1
