Given numbers are 420,723,386,364,758
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,723,386,364,758 is 96251211420.
Find LCM of 420,723,386,364,758 with Prime Factorization
| 2 | 420, 723, 386, 364, 758 |
| 2 | 210, 723, 193, 182, 379 |
| 3 | 105, 723, 193, 91, 379 |
| 7 | 35, 241, 193, 91, 379 |
| 5, 241, 193, 13, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 241 x 193 x 13 x 379 = 96251211420
Therefore, the lowest common multiple of 420,723,386,364,758 is 96251211420.
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.
420 x 723 x 386 x 364 x 758 = 32340407037120
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.
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
723 : 1, 3, 241, 723
386 : 1, 2, 193, 386
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,723,386,364,758, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
723:3x 241
386:2x 193
364:2x 2x 7x 13
758:2x 379
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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 32340407037120/(1x336)
LCM = 32340407037120/336
LCM = 96251211420
Thus, we can understand that the LCM of 420,723,386,364,758 is 96251211420.
