Given numbers are 619,656,870,174
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,656,870,174 is 176637840.
Find LCM of 619,656,870,174 with Prime Factorization
| 2 | 619, 656, 870, 174 |
| 3 | 619, 328, 435, 87 |
| 29 | 619, 328, 145, 29 |
| 619, 328, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 619 x 328 x 5 x 1 = 176637840
Therefore, the lowest common multiple of 619,656,870,174 is 176637840.
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.
619 x 656 x 870 x 174 = 61469968320
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.
619 : 1, 619
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
174 : 1, 2, 3, 6, 29, 58, 87, 174
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,656,870,174, is 1.
Now, the common factors can be found like this.
619:619
656:2x 2x 2x 2x 41
870:2x 3x 5x 29
174:2x 3x 29
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 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 61469968320/(1x348)
LCM = 61469968320/348
LCM = 176637840
Thus, we can understand that the LCM of 619,656,870,174 is 176637840.
