Given numbers are 476,159,770,674,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,159,770,674,557 is 781361237580.
Find LCM of 476,159,770,674,557 with Prime Factorization
| 2 | 476, 159, 770, 674, 557 |
| 7 | 238, 159, 385, 337, 557 |
| 34, 159, 55, 337, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 34 x 159 x 55 x 337 x 557 = 781361237580
Therefore, the lowest common multiple of 476,159,770,674,557 is 781361237580.
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.
476 x 159 x 770 x 674 x 557 = 21878114652240
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
159 : 1, 3, 53, 159
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
674 : 1, 2, 337, 674
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,159,770,674,557, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
159:3x 53
770:2x 5x 7x 11
674:2x 337
557:557
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 7 = 28
Therefore, the value for common factors is 28.
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 = 21878114652240/(1x28)
LCM = 21878114652240/28
LCM = 781361237580
Thus, we can understand that the LCM of 476,159,770,674,557 is 781361237580.
