Given numbers are 643, 464, 158, 376

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

Apply this formula for all numbers.

Step1:

LCM(643, 464) = 298352

GCD(643, 464) = ( 643 x 464 ) / 298352

= 643 / 464

= 643

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

Step3:

LCM(1, 376) = 376

GCD(1, 376) = ( 1 x 376 ) / 376

= 1 / 376

= 1

So, Greatest Common Divisor of 643, 464, 158, 376 is 1
