Given numbers are 394, 853, 639, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 853) = 336082
GCD(394, 853) = ( 394 x 853 ) / 336082
= 394 / 853
= 394
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
So, Greatest Common Divisor of 394, 853, 639, 251 is 1
