Given numbers are 643, 390, 532, 119

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

Apply this formula for all numbers.

Step1:

LCM(643, 390) = 250770

GCD(643, 390) = ( 643 x 390 ) / 250770

= 643 / 390

= 643

Step2:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

Step3:

LCM(1, 119) = 119

GCD(1, 119) = ( 1 x 119 ) / 119

= 1 / 119

= 1

So, Greatest Common Divisor of 643, 390, 532, 119 is 1
