Given numbers are 301,396,781,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 301,396,781,357 is 143869572.
Find LCM of 301,396,781,357 with Prime Factorization
| 3 | 301, 396, 781, 357 |
| 7 | 301, 132, 781, 119 |
| 11 | 43, 132, 781, 17 |
| 43, 12, 71, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 43 x 12 x 71 x 17 = 143869572
Therefore, the lowest common multiple of 301,396,781,357 is 143869572.
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.
301 x 396 x 781 x 357 = 33233871132
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.
301 : 1, 7, 43, 301
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
781 : 1, 11, 71, 781
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 301,396,781,357, is 1.
Now, the common factors can be found like this.
301:7x 43
396:2x 2x 3x 3x 11
781:11x 71
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 33233871132/(1x231)
LCM = 33233871132/231
LCM = 143869572
Thus, we can understand that the LCM of 301,396,781,357 is 143869572.
