Given numbers are 403,343,451,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,343,451,931 is 1184484301.
Find LCM of 403,343,451,931 with Prime Factorization
7 | 403, 343, 451, 931 |
7 | 403, 49, 451, 133 |
403, 7, 451, 19 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 403 x 7 x 451 x 19 = 1184484301
Therefore, the lowest common multiple of 403,343,451,931 is 1184484301.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
403 x 343 x 451 x 931 = 58039730749
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
403 : 1, 13, 31, 403
343 : 1, 7, 49, 343
451 : 1, 11, 41, 451
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,343,451,931, is 1.
Now, the common factors can be found like this.
403:13x 31
343:7x 7x 7
451:11x 41
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 58039730749/(1x49)
LCM = 58039730749/49
LCM = 1184484301
Thus, we can understand that the LCM of 403,343,451,931 is 1184484301.
