Find LCM of 924,561,497,415,142 with Prime Factorization
| 2 | 924, 561, 497, 415, 142 |
| 3 | 462, 561, 497, 415, 71 |
| 7 | 154, 187, 497, 415, 71 |
| 11 | 22, 187, 71, 415, 71 |
| 71 | 2, 17, 71, 415, 71 |
| 2, 17, 1, 415, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 71 x 2 x 17 x 1 x 415 x 1 = 462836220
Therefore, the lowest common multiple of 924,561,497,415,142 is 462836220.
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.
924 x 561 x 497 x 415 x 142 = 15181953688440
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
561 : 1, 3, 11, 17, 33, 51, 187, 561
497 : 1, 7, 71, 497
415 : 1, 5, 83, 415
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,561,497,415,142, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
561:3x 11x 17
497:7x 71
415:5x 83
142:2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11x 71 = 32802
Therefore, the value for common factors is 32802.
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 = 15181953688440/(1x32802)
LCM = 15181953688440/32802
LCM = 462836220
Thus, we can understand that the LCM of 924,561,497,415,142 is 462836220.
