Given numbers are 462,655,787,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,655,787,160 is 3810465120.
Find LCM of 462,655,787,160 with Prime Factorization
| 2 | 462, 655, 787, 160 |
| 5 | 231, 655, 787, 80 |
| 231, 131, 787, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 231 x 131 x 787 x 16 = 3810465120
Therefore, the lowest common multiple of 462,655,787,160 is 3810465120.
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.
462 x 655 x 787 x 160 = 38104651200
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
655 : 1, 5, 131, 655
787 : 1, 787
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,655,787,160, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
655:5x 131
787:787
160:2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 38104651200/(1x10)
LCM = 38104651200/10
LCM = 3810465120
Thus, we can understand that the LCM of 462,655,787,160 is 3810465120.
