Given numbers are 628, 456, 289, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 456) = 71592
GCD(628, 456) = ( 628 x 456 ) / 71592
= 628 / 456
= 628
Step2:
LCM(4, 289) = 1156
GCD(4, 289) = ( 4 x 289 ) / 1156
= 4 / 289
= 4
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 628, 456, 289, 210 is 1
