Given numbers are 194,689,638,653,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 194,689,638,653,628 is 8742878927068.
Find LCM of 194,689,638,653,628 with Prime Factorization
2 | 194, 689, 638, 653, 628 |
97, 689, 319, 653, 314 |
Multiply the prime numbers at the bottom and the left side.
2 x 97 x 689 x 319 x 653 x 314 = 8742878927068
Therefore, the lowest common multiple of 194,689,638,653,628 is 8742878927068.
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.
194 x 689 x 638 x 653 x 628 = 34971515708272
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.
194 : 1, 2, 97, 194
689 : 1, 13, 53, 689
638 : 1, 2, 11, 22, 29, 58, 319, 638
653 : 1, 653
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,689,638,653,628, is 1.
Now, the common factors can be found like this.
194:2x 97
689:13x 53
638:2x 11x 29
653:653
628:2x 2x 157
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 = 34971515708272/(1x4)
LCM = 34971515708272/4
LCM = 8742878927068
Thus, we can understand that the LCM of 194,689,638,653,628 is 8742878927068.
