Given numbers are 975, 643, 306, 178

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

Apply this formula for all numbers.

Step1:

LCM(975, 643) = 626925

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

= 975 / 643

= 975

Step2:

LCM(1, 306) = 306

GCD(1, 306) = ( 1 x 306 ) / 306

= 1 / 306

= 1

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 975, 643, 306, 178 is 1
