Given numbers are 643, 975, 820, 935

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

Apply this formula for all numbers.

Step1:

LCM(643, 975) = 626925

GCD(643, 975) = ( 643 x 975 ) / 626925

= 643 / 975

= 643

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

So, Greatest Common Divisor of 643, 975, 820, 935 is 1
