Given numbers are 967,846,420,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 967,846,420,478 is 13686511860.
Find LCM of 967,846,420,478 with Prime Factorization
| 2 | 967, 846, 420, 478 |
| 3 | 967, 423, 210, 239 |
| 967, 141, 70, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 967 x 141 x 70 x 239 = 13686511860
Therefore, the lowest common multiple of 967,846,420,478 is 13686511860.
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.
967 x 846 x 420 x 478 = 164238142320
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.
967 : 1, 967
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 967,846,420,478, is 1.
Now, the common factors can be found like this.
967:967
846:2x 3x 3x 47
420:2x 2x 3x 5x 7
478:2x 239
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 3 = 12
Therefore, the value for common factors is 12.
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 = 164238142320/(1x12)
LCM = 164238142320/12
LCM = 13686511860
Thus, we can understand that the LCM of 967,846,420,478 is 13686511860.
