Given numbers are 398, 521, 392, 907

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

Apply this formula for all numbers.

Step1:

LCM(398, 521) = 207358

GCD(398, 521) = ( 398 x 521 ) / 207358

= 398 / 521

= 398

Step2:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 398, 521, 392, 907 is 1
