Given numbers are 790,911,948,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,911,948,970 is 418859580.
Find LCM of 790,911,948,970 with Prime Factorization
| 2 | 790, 911, 948, 970 |
| 5 | 395, 911, 474, 485 |
| 79 | 79, 911, 474, 97 |
| 1, 911, 6, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 1 x 911 x 6 x 97 = 418859580
Therefore, the lowest common multiple of 790,911,948,970 is 418859580.
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.
790 x 911 x 948 x 970 = 661798136400
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
911 : 1, 911
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,911,948,970, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
911:911
948:2x 2x 3x 79
970:2x 5x 97
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 5x 79 = 1580
Therefore, the value for common factors is 1580.
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 = 661798136400/(1x1580)
LCM = 661798136400/1580
LCM = 418859580
Thus, we can understand that the LCM of 790,911,948,970 is 418859580.
