Given numbers are 553,156,637,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 553,156,637,286 is 6642636.
Find LCM of 553,156,637,286 with Prime Factorization
| 2 | 553, 156, 637, 286 |
| 7 | 553, 78, 637, 143 |
| 13 | 79, 78, 91, 143 |
| 79, 6, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 79 x 6 x 7 x 11 = 6642636
Therefore, the lowest common multiple of 553,156,637,286 is 6642636.
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.
553 x 156 x 637 x 286 = 15716476776
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.
553 : 1, 7, 79, 553
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
637 : 1, 7, 13, 49, 91, 637
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,156,637,286, is 1.
Now, the common factors can be found like this.
553:7x 79
156:2x 2x 3x 13
637:7x 7x 13
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13x 13 = 2366
Therefore, the value for common factors is 2366.
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 = 15716476776/(1x2366)
LCM = 15716476776/2366
LCM = 6642636
Thus, we can understand that the LCM of 553,156,637,286 is 6642636.
