Given numbers are 438,653,651,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,653,651,651 is 62065038.
Find LCM of 438,653,651,651 with Prime Factorization
| 3 | 438, 653, 651, 651 |
| 7 | 146, 653, 217, 217 |
| 31 | 146, 653, 31, 31 |
| 146, 653, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 31 x 146 x 653 x 1 x 1 = 62065038
Therefore, the lowest common multiple of 438,653,651,651 is 62065038.
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.
438 x 653 x 651 x 651 = 121213019214
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
653 : 1, 653
651 : 1, 3, 7, 21, 31, 93, 217, 651
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,653,651,651, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
653:653
651:3x 7x 31
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 31 = 1953
Therefore, the value for common factors is 1953.
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 = 121213019214/(1x1953)
LCM = 121213019214/1953
LCM = 62065038
Thus, we can understand that the LCM of 438,653,651,651 is 62065038.
