Given numbers are 142,639,853,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,639,853,618 is 112283802.
Find LCM of 142,639,853,618 with Prime Factorization
| 2 | 142, 639, 853, 618 |
| 3 | 71, 639, 853, 309 |
| 71 | 71, 213, 853, 103 |
| 1, 3, 853, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 1 x 3 x 853 x 103 = 112283802
Therefore, the lowest common multiple of 142,639,853,618 is 112283802.
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.
142 x 639 x 853 x 618 = 47832899652
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.
142 : 1, 2, 71, 142
639 : 1, 3, 9, 71, 213, 639
853 : 1, 853
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,639,853,618, is 1.
Now, the common factors can be found like this.
142:2x 71
639:3x 3x 71
853:853
618:2x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 71 = 426
Therefore, the value for common factors is 426.
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 = 47832899652/(1x426)
LCM = 47832899652/426
LCM = 112283802
Thus, we can understand that the LCM of 142,639,853,618 is 112283802.
