Given numbers are 643, 408, 374, 533

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

Apply this formula for all numbers.

Step1:

LCM(643, 408) = 262344

GCD(643, 408) = ( 643 x 408 ) / 262344

= 643 / 408

= 643

Step2:

LCM(1, 374) = 374

GCD(1, 374) = ( 1 x 374 ) / 374

= 1 / 374

= 1

Step3:

LCM(1, 533) = 533

GCD(1, 533) = ( 1 x 533 ) / 533

= 1 / 533

= 1

So, Greatest Common Divisor of 643, 408, 374, 533 is 1
