Given numbers are 740,329,551,842,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,329,551,842,172 is 2428453365380.
Find LCM of 740,329,551,842,172 with Prime Factorization
| 2 | 740, 329, 551, 842, 172 |
| 2 | 370, 329, 551, 421, 86 |
| 185, 329, 551, 421, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 185 x 329 x 551 x 421 x 43 = 2428453365380
Therefore, the lowest common multiple of 740,329,551,842,172 is 2428453365380.
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.
740 x 329 x 551 x 842 x 172 = 19427626923040
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
329 : 1, 7, 47, 329
551 : 1, 19, 29, 551
842 : 1, 2, 421, 842
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,329,551,842,172, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
329:7x 47
551:19x 29
842:2x 421
172:2x 2x 43
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 2 = 8
Therefore, the value for common factors is 8.
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 = 19427626923040/(1x8)
LCM = 19427626923040/8
LCM = 2428453365380
Thus, we can understand that the LCM of 740,329,551,842,172 is 2428453365380.
