Given numbers are 154,139,968,369
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,139,968,369 is 347547816.
Find LCM of 154,139,968,369 with Prime Factorization
| 2 | 154, 139, 968, 369 |
| 11 | 77, 139, 484, 369 |
| 7, 139, 44, 369 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 7 x 139 x 44 x 369 = 347547816
Therefore, the lowest common multiple of 154,139,968,369 is 347547816.
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.
154 x 139 x 968 x 369 = 7646051952
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
139 : 1, 139
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,139,968,369, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
139:139
968:2x 2x 2x 11x 11
369:3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 7646051952/(1x22)
LCM = 7646051952/22
LCM = 347547816
Thus, we can understand that the LCM of 154,139,968,369 is 347547816.
