Given numbers are 551, 406, 258, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(551, 406) = 7714
GCD(551, 406) = ( 551 x 406 ) / 7714
= 551 / 406
= 551
Step2:
LCM(29, 258) = 7482
GCD(29, 258) = ( 29 x 258 ) / 7482
= 29 / 258
= 29
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 551, 406, 258, 781 is 1
