Given numbers are 688, 408, 972, 283

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

Apply this formula for all numbers.

Step1:

LCM(688, 408) = 35088

GCD(688, 408) = ( 688 x 408 ) / 35088

= 688 / 408

= 688

Step2:

LCM(8, 972) = 1944

GCD(8, 972) = ( 8 x 972 ) / 1944

= 8 / 972

= 8

Step3:

LCM(4, 283) = 1132

GCD(4, 283) = ( 4 x 283 ) / 1132

= 4 / 283

= 4

So, Greatest Common Divisor of 688, 408, 972, 283 is 1
