Given numbers are 178, 688, 70, 975

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

Apply this formula for all numbers.

Step1:

LCM(178, 688) = 61232

GCD(178, 688) = ( 178 x 688 ) / 61232

= 178 / 688

= 178

Step2:

LCM(2, 70) = 70

GCD(2, 70) = ( 2 x 70 ) / 70

= 2 / 70

= 2

Step3:

LCM(2, 975) = 1950

GCD(2, 975) = ( 2 x 975 ) / 1950

= 2 / 975

= 2

So, Greatest Common Divisor of 178, 688, 70, 975 is 1
