Given numbers are 749,688,842,282
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,688,842,282 is 30589435632.
Find LCM of 749,688,842,282 with Prime Factorization
| 2 | 749, 688, 842, 282 |
| 749, 344, 421, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 749 x 344 x 421 x 141 = 30589435632
Therefore, the lowest common multiple of 749,688,842,282 is 30589435632.
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.
749 x 688 x 842 x 282 = 122357742528
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.
749 : 1, 7, 107, 749
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
842 : 1, 2, 421, 842
282 : 1, 2, 3, 6, 47, 94, 141, 282
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,688,842,282, is 1.
Now, the common factors can be found like this.
749:7x 107
688:2x 2x 2x 2x 43
842:2x 421
282:2x 3x 47
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 = 122357742528/(1x4)
LCM = 122357742528/4
LCM = 30589435632
Thus, we can understand that the LCM of 749,688,842,282 is 30589435632.
