Find LCM of 403,507,902,812,840 with Prime Factorization
| 2 | 403, 507, 902, 812, 840 |
| 2 | 403, 507, 451, 406, 420 |
| 3 | 403, 507, 451, 203, 210 |
| 7 | 403, 169, 451, 203, 70 |
| 13 | 403, 169, 451, 29, 10 |
| 31, 13, 451, 29, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 31 x 13 x 451 x 29 x 10 = 57557540040
Therefore, the lowest common multiple of 403,507,902,812,840 is 57557540040.
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 507 x 902 x 812 x 840 = 125705667447360
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
507 : 1, 3, 13, 39, 169, 507
902 : 1, 2, 11, 22, 41, 82, 451, 902
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,507,902,812,840, is 1.
Now, the common factors can be found like this.
403:13x 31
507:3x 13x 13
902:2x 11x 41
812:2x 2x 7x 29
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 125705667447360/(1x2184)
LCM = 125705667447360/2184
LCM = 57557540040
Thus, we can understand that the LCM of 403,507,902,812,840 is 57557540040.
