Given numbers are 408, 726, 210, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 726) = 49368
GCD(408, 726) = ( 408 x 726 ) / 49368
= 408 / 726
= 408
Step2:
LCM(6, 210) = 210
GCD(6, 210) = ( 6 x 210 ) / 210
= 6 / 210
= 6
Step3:
LCM(6, 257) = 1542
GCD(6, 257) = ( 6 x 257 ) / 1542
= 6 / 257
= 6
So, Greatest Common Divisor of 408, 726, 210, 257 is 1
