Given numbers are 770,392,121,157,758
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,392,121,157,758 is 14111731480.
Find LCM of 770,392,121,157,758 with Prime Factorization
| 2 | 770, 392, 121, 157, 758 |
| 7 | 385, 196, 121, 157, 379 |
| 11 | 55, 28, 121, 157, 379 |
| 5, 28, 11, 157, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 5 x 28 x 11 x 157 x 379 = 14111731480
Therefore, the lowest common multiple of 770,392,121,157,758 is 14111731480.
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.
770 x 392 x 121 x 157 x 758 = 4346413295840
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
121 : 1, 11, 121
157 : 1, 157
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,392,121,157,758, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
392:2x 2x 2x 7x 7
121:11x 11
157:157
758:2x 379
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 4346413295840/(1x308)
LCM = 4346413295840/308
LCM = 14111731480
Thus, we can understand that the LCM of 770,392,121,157,758 is 14111731480.
