Given numbers are 821,376,624,740,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,376,624,740,724 is 806261473680.
Find LCM of 821,376,624,740,724 with Prime Factorization
| 2 | 821, 376, 624, 740, 724 |
| 2 | 821, 188, 312, 370, 362 |
| 2 | 821, 94, 156, 185, 181 |
| 821, 47, 78, 185, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 821 x 47 x 78 x 185 x 181 = 806261473680
Therefore, the lowest common multiple of 821,376,624,740,724 is 806261473680.
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.
821 x 376 x 624 x 740 x 724 = 103201468631040
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.
821 : 1, 821
376 : 1, 2, 4, 8, 47, 94, 188, 376
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,376,624,740,724, is 1.
Now, the common factors can be found like this.
821:821
376:2x 2x 2x 47
624:2x 2x 2x 2x 3x 13
740:2x 2x 5x 37
724:2x 2x 181
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 2x 2x 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 103201468631040/(1x128)
LCM = 103201468631040/128
LCM = 806261473680
Thus, we can understand that the LCM of 821,376,624,740,724 is 806261473680.
