Given numbers are 578,491,689,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,491,689,658 is 64331614438.
Find LCM of 578,491,689,658 with Prime Factorization
| 2 | 578, 491, 689, 658 |
| 289, 491, 689, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 289 x 491 x 689 x 329 = 64331614438
Therefore, the lowest common multiple of 578,491,689,658 is 64331614438.
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.
578 x 491 x 689 x 658 = 128663228876
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.
578 : 1, 2, 17, 34, 289, 578
491 : 1, 491
689 : 1, 13, 53, 689
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,491,689,658, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
491:491
689:13x 53
658:2x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 128663228876/(1x2)
LCM = 128663228876/2
LCM = 64331614438
Thus, we can understand that the LCM of 578,491,689,658 is 64331614438.
