Given numbers are 469,965,386,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,965,386,420 is 5431020.
Find LCM of 469,965,386,420 with Prime Factorization
| 2 | 469, 965, 386, 420 |
| 5 | 469, 965, 193, 210 |
| 7 | 469, 193, 193, 42 |
| 193 | 67, 193, 193, 6 |
| 67, 1, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 193 x 67 x 1 x 1 x 6 = 5431020
Therefore, the lowest common multiple of 469,965,386,420 is 5431020.
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.
469 x 965 x 386 x 420 = 73373080200
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.
469 : 1, 7, 67, 469
965 : 1, 5, 193, 965
386 : 1, 2, 193, 386
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,965,386,420, is 1.
Now, the common factors can be found like this.
469:7x 67
965:5x 193
386:2x 193
420:2x 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 5x 7x 193 = 13510
Therefore, the value for common factors is 13510.
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 = 73373080200/(1x13510)
LCM = 73373080200/13510
LCM = 5431020
Thus, we can understand that the LCM of 469,965,386,420 is 5431020.
