Given numbers are 643, 356, 508, 379

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

Apply this formula for all numbers.

Step1:

LCM(643, 356) = 228908

GCD(643, 356) = ( 643 x 356 ) / 228908

= 643 / 356

= 643

Step2:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

Step3:

LCM(1, 379) = 379

GCD(1, 379) = ( 1 x 379 ) / 379

= 1 / 379

= 1

So, Greatest Common Divisor of 643, 356, 508, 379 is 1
