Find LCM of 724,919,820,399,465 with Prime Factorization
| 2 | 724, 919, 820, 399, 465 |
| 2 | 362, 919, 410, 399, 465 |
| 3 | 181, 919, 205, 399, 465 |
| 5 | 181, 919, 205, 133, 155 |
| 181, 919, 41, 133, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 181 x 919 x 41 x 133 x 31 = 1687106614620
Therefore, the lowest common multiple of 724,919,820,399,465 is 1687106614620.
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.
724 x 919 x 820 x 399 x 465 = 101226396877200
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.
724 : 1, 2, 4, 181, 362, 724
919 : 1, 919
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
399 : 1, 3, 7, 19, 21, 57, 133, 399
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,919,820,399,465, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
919:919
820:2x 2x 5x 41
399:3x 7x 19
465:3x 5x 31
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 5 = 60
Therefore, the value for common factors is 60.
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 = 101226396877200/(1x60)
LCM = 101226396877200/60
LCM = 1687106614620
Thus, we can understand that the LCM of 724,919,820,399,465 is 1687106614620.
