Find LCM of 420,501,115,238,828 with Prime Factorization
2 | 420, 501, 115, 238, 828 |
2 | 210, 501, 115, 119, 414 |
3 | 105, 501, 115, 119, 207 |
5 | 35, 167, 115, 119, 69 |
7 | 7, 167, 23, 119, 69 |
23 | 1, 167, 23, 17, 69 |
1, 167, 1, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 23 x 1 x 167 x 1 x 17 x 3 = 82274220
Therefore, the lowest common multiple of 420,501,115,238,828 is 82274220.
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 501 x 115 x 238 x 828 = 4768613791200
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
501 : 1, 3, 167, 501
115 : 1, 5, 23, 115
238 : 1, 2, 7, 14, 17, 34, 119, 238
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,501,115,238,828, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
501:3x 167
115:5x 23
238:2x 7x 17
828:2x 2x 3x 3x 23
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 3x 3x 5x 7x 23 = 57960
Therefore, the value for common factors is 57960.
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 = 4768613791200/(1x57960)
LCM = 4768613791200/57960
LCM = 82274220
Thus, we can understand that the LCM of 420,501,115,238,828 is 82274220.
