Given numbers are 319,441,220,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,441,220,138 is 64712340.
Find LCM of 319,441,220,138 with Prime Factorization
2 | 319, 441, 220, 138 |
3 | 319, 441, 110, 69 |
11 | 319, 147, 110, 23 |
29, 147, 10, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 147 x 10 x 23 = 64712340
Therefore, the lowest common multiple of 319,441,220,138 is 64712340.
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.
319 x 441 x 220 x 138 = 4271014440
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.
319 : 1, 11, 29, 319
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,441,220,138, is 1.
Now, the common factors can be found like this.
319:11x 29
441:3x 3x 7x 7
220:2x 2x 5x 11
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 4271014440/(1x66)
LCM = 4271014440/66
LCM = 64712340
Thus, we can understand that the LCM of 319,441,220,138 is 64712340.
