Given numbers are 539,661,642,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 539,661,642,956 is 109333474404.
Find LCM of 539,661,642,956 with Prime Factorization
| 2 | 539, 661, 642, 956 |
| 539, 661, 321, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 539 x 661 x 321 x 478 = 109333474404
Therefore, the lowest common multiple of 539,661,642,956 is 109333474404.
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.
539 x 661 x 642 x 956 = 218666948808
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.
539 : 1, 7, 11, 49, 77, 539
661 : 1, 661
642 : 1, 2, 3, 6, 107, 214, 321, 642
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 539,661,642,956, is 1.
Now, the common factors can be found like this.
539:7x 7x 11
661:661
642:2x 3x 107
956:2x 2x 239
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 = 218666948808/(1x2)
LCM = 218666948808/2
LCM = 109333474404
Thus, we can understand that the LCM of 539,661,642,956 is 109333474404.
