Find LCM of 147,404,912,721,521 with Prime Factorization
| 2 | 147, 404, 912, 721, 521 |
| 2 | 147, 202, 456, 721, 521 |
| 3 | 147, 101, 228, 721, 521 |
| 7 | 49, 101, 76, 721, 521 |
| 7, 101, 76, 103, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 101 x 76 x 103 x 521 = 242207306544
Therefore, the lowest common multiple of 147,404,912,721,521 is 242207306544.
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.
147 x 404 x 912 x 721 x 521 = 20345413749696
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.
147 : 1, 3, 7, 21, 49, 147
404 : 1, 2, 4, 101, 202, 404
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
721 : 1, 7, 103, 721
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,404,912,721,521, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
404:2x 2x 101
912:2x 2x 2x 2x 3x 19
721:7x 103
521:521
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 20345413749696/(1x84)
LCM = 20345413749696/84
LCM = 242207306544
Thus, we can understand that the LCM of 147,404,912,721,521 is 242207306544.
