Given numbers are 970,578,980,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,578,980,868 is 851642540.
Find LCM of 970,578,980,868 with Prime Factorization
| 2 | 970, 578, 980, 868 |
| 2 | 485, 289, 490, 434 |
| 5 | 485, 289, 245, 217 |
| 7 | 97, 289, 49, 217 |
| 97, 289, 7, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 97 x 289 x 7 x 31 = 851642540
Therefore, the lowest common multiple of 970,578,980,868 is 851642540.
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.
970 x 578 x 980 x 868 = 476919822400
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
578 : 1, 2, 17, 34, 289, 578
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,578,980,868, is 2.
Now, the common factors can be found like this.
970:2x 5x 97
578:2x 17x 17
980:2x 2x 5x 7x 7
868:2x 2x 7x 31
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 476919822400/(2x280)
LCM = 476919822400/560
LCM = 851642540
Thus, we can understand that the LCM of 970,578,980,868 is 851642540.
