Given numbers are 728,748,411,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,748,411,635 is 35529453960.
Find LCM of 728,748,411,635 with Prime Factorization
2 | 728, 748, 411, 635 |
2 | 364, 374, 411, 635 |
182, 187, 411, 635 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 182 x 187 x 411 x 635 = 35529453960
Therefore, the lowest common multiple of 728,748,411,635 is 35529453960.
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.
728 x 748 x 411 x 635 = 142117815840
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
411 : 1, 3, 137, 411
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,748,411,635, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
748:2x 2x 11x 17
411:3x 137
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 142117815840/(1x4)
LCM = 142117815840/4
LCM = 35529453960
Thus, we can understand that the LCM of 728,748,411,635 is 35529453960.
