Given numbers are 460,695,436,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,695,436,128 is 223022720.
Find LCM of 460,695,436,128 with Prime Factorization
2 | 460, 695, 436, 128 |
2 | 230, 695, 218, 64 |
5 | 115, 695, 109, 32 |
23, 139, 109, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 139 x 109 x 32 = 223022720
Therefore, the lowest common multiple of 460,695,436,128 is 223022720.
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.
460 x 695 x 436 x 128 = 17841817600
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
695 : 1, 5, 139, 695
436 : 1, 2, 4, 109, 218, 436
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,695,436,128, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
695:5x 139
436:2x 2x 109
128:2x 2x 2x 2x 2x 2x 2
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 17841817600/(1x80)
LCM = 17841817600/80
LCM = 223022720
Thus, we can understand that the LCM of 460,695,436,128 is 223022720.
