Given numbers are 767,695,721,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 767,695,721,278 is 768679730.
Find LCM of 767,695,721,278 with Prime Factorization
| 139 | 767, 695, 721, 278 |
| 767, 5, 721, 2 |
Multiply the prime numbers at the bottom and the left side.
139 x 767 x 5 x 721 x 2 = 768679730
Therefore, the lowest common multiple of 767,695,721,278 is 768679730.
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.
767 x 695 x 721 x 278 = 106846482470
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.
767 : 1, 13, 59, 767
695 : 1, 5, 139, 695
721 : 1, 7, 103, 721
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,695,721,278, is 1.
Now, the common factors can be found like this.
767:13x 59
695:5x 139
721:7x 103
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
139 = 139
Therefore, the value for common factors is 139.
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 = 106846482470/(1x139)
LCM = 106846482470/139
LCM = 768679730
Thus, we can understand that the LCM of 767,695,721,278 is 768679730.
