Given numbers are 318,221,708,830,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,221,708,830,742 is 24090595620.
Find LCM of 318,221,708,830,742 with Prime Factorization
| 2 | 318, 221, 708, 830, 742 |
| 3 | 159, 221, 354, 415, 371 |
| 53 | 53, 221, 118, 415, 371 |
| 1, 221, 118, 415, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 1 x 221 x 118 x 415 x 7 = 24090595620
Therefore, the lowest common multiple of 318,221,708,830,742 is 24090595620.
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.
318 x 221 x 708 x 830 x 742 = 30643237628640
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
221 : 1, 13, 17, 221
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
830 : 1, 2, 5, 10, 83, 166, 415, 830
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,221,708,830,742, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
221:13x 17
708:2x 2x 3x 59
830:2x 5x 83
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 53 = 1272
Therefore, the value for common factors is 1272.
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 = 30643237628640/(1x1272)
LCM = 30643237628640/1272
LCM = 24090595620
Thus, we can understand that the LCM of 318,221,708,830,742 is 24090595620.
