Given numbers are 372,490,246,646,619
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 372,490,246,646,619 is 747112585380.
Find LCM of 372,490,246,646,619 with Prime Factorization
| 2 | 372, 490, 246, 646, 619 |
| 3 | 186, 245, 123, 323, 619 |
| 62, 245, 41, 323, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 62 x 245 x 41 x 323 x 619 = 747112585380
Therefore, the lowest common multiple of 372,490,246,646,619 is 747112585380.
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.
372 x 490 x 246 x 646 x 619 = 17930702049120
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
246 : 1, 2, 3, 6, 41, 82, 123, 246
646 : 1, 2, 17, 19, 34, 38, 323, 646
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,490,246,646,619, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
490:2x 5x 7x 7
246:2x 3x 41
646:2x 17x 19
619:619
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 3 = 24
Therefore, the value for common factors is 24.
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 = 17930702049120/(1x24)
LCM = 17930702049120/24
LCM = 747112585380
Thus, we can understand that the LCM of 372,490,246,646,619 is 747112585380.
