Given numbers are 961,754,686,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,754,686,355 is 88230188410.
Find LCM of 961,754,686,355 with Prime Factorization
| 2 | 961, 754, 686, 355 |
| 961, 377, 343, 355 |
Multiply the prime numbers at the bottom and the left side.
2 x 961 x 377 x 343 x 355 = 88230188410
Therefore, the lowest common multiple of 961,754,686,355 is 88230188410.
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.
961 x 754 x 686 x 355 = 176460376820
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.
961 : 1, 31, 961
754 : 1, 2, 13, 26, 29, 58, 377, 754
686 : 1, 2, 7, 14, 49, 98, 343, 686
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,754,686,355, is 1.
Now, the common factors can be found like this.
961:31x 31
754:2x 13x 29
686:2x 7x 7x 7
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 176460376820/(1x2)
LCM = 176460376820/2
LCM = 88230188410
Thus, we can understand that the LCM of 961,754,686,355 is 88230188410.
