Given numbers are 628, 172, 387, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 172) = 27004
GCD(628, 172) = ( 628 x 172 ) / 27004
= 628 / 172
= 628
Step2:
LCM(4, 387) = 1548
GCD(4, 387) = ( 4 x 387 ) / 1548
= 4 / 387
= 4
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 628, 172, 387, 311 is 1
