Given numbers are 638,533,724,243,372
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,533,724,243,372 is 927308895084.
Find LCM of 638,533,724,243,372 with Prime Factorization
| 2 | 638, 533, 724, 243, 372 |
| 2 | 319, 533, 362, 243, 186 |
| 3 | 319, 533, 181, 243, 93 |
| 319, 533, 181, 81, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 319 x 533 x 181 x 81 x 31 = 927308895084
Therefore, the lowest common multiple of 638,533,724,243,372 is 927308895084.
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.
638 x 533 x 724 x 243 x 372 = 22255413482016
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
533 : 1, 13, 41, 533
724 : 1, 2, 4, 181, 362, 724
243 : 1, 3, 9, 27, 81, 243
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,533,724,243,372, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
533:13x 41
724:2x 2x 181
243:3x 3x 3x 3x 3
372:2x 2x 3x 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 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 = 22255413482016/(1x24)
LCM = 22255413482016/24
LCM = 927308895084
Thus, we can understand that the LCM of 638,533,724,243,372 is 927308895084.
