Given numbers are 947,798,762,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,798,762,220 is 10557212820.
Find LCM of 947,798,762,220 with Prime Factorization
| 2 | 947, 798, 762, 220 |
| 3 | 947, 399, 381, 110 |
| 947, 133, 127, 110 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 947 x 133 x 127 x 110 = 10557212820
Therefore, the lowest common multiple of 947,798,762,220 is 10557212820.
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.
947 x 798 x 762 x 220 = 126686553840
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.
947 : 1, 947
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
762 : 1, 2, 3, 6, 127, 254, 381, 762
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,798,762,220, is 1.
Now, the common factors can be found like this.
947:947
798:2x 3x 7x 19
762:2x 3x 127
220:2x 2x 5x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 126686553840/(1x12)
LCM = 126686553840/12
LCM = 10557212820
Thus, we can understand that the LCM of 947,798,762,220 is 10557212820.
