Given numbers are 819,710,615,917,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,710,615,917,423 is 146789591130.
Find LCM of 819,710,615,917,423 with Prime Factorization
| 3 | 819, 710, 615, 917, 423 |
| 3 | 273, 710, 205, 917, 141 |
| 5 | 91, 710, 205, 917, 47 |
| 7 | 91, 142, 41, 917, 47 |
| 13, 142, 41, 131, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 13 x 142 x 41 x 131 x 47 = 146789591130
Therefore, the lowest common multiple of 819,710,615,917,423 is 146789591130.
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.
819 x 710 x 615 x 917 x 423 = 138716163617850
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
710 : 1, 2, 5, 10, 71, 142, 355, 710
615 : 1, 3, 5, 15, 41, 123, 205, 615
917 : 1, 7, 131, 917
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,710,615,917,423, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
710:2x 5x 71
615:3x 5x 41
917:7x 131
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 138716163617850/(1x945)
LCM = 138716163617850/945
LCM = 146789591130
Thus, we can understand that the LCM of 819,710,615,917,423 is 146789591130.
