Given numbers are 157, 620, 447, 471

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

Apply this formula for all numbers.

Step1:

LCM(157, 620) = 97340

GCD(157, 620) = ( 157 x 620 ) / 97340

= 157 / 620

= 157

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

So, Greatest Common Divisor of 157, 620, 447, 471 is 1
