Given numbers are 307,209,817,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 307,209,817,154 is 38626126.
Find LCM of 307,209,817,154 with Prime Factorization
11 | 307, 209, 817, 154 |
19 | 307, 19, 817, 14 |
307, 1, 43, 14 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 307 x 1 x 43 x 14 = 38626126
Therefore, the lowest common multiple of 307,209,817,154 is 38626126.
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.
307 x 209 x 817 x 154 = 8072860334
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.
307 : 1, 307
209 : 1, 11, 19, 209
817 : 1, 19, 43, 817
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,209,817,154, is 1.
Now, the common factors can be found like this.
307:307
209:11x 19
817:19x 43
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 8072860334/(1x209)
LCM = 8072860334/209
LCM = 38626126
Thus, we can understand that the LCM of 307,209,817,154 is 38626126.
