Given numbers are 314,931,980,426
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 314,931,980,426 is 622671420.
Find LCM of 314,931,980,426 with Prime Factorization
| 2 | 314, 931, 980, 426 |
| 7 | 157, 931, 490, 213 |
| 7 | 157, 133, 70, 213 |
| 157, 19, 10, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 157 x 19 x 10 x 213 = 622671420
Therefore, the lowest common multiple of 314,931,980,426 is 622671420.
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.
314 x 931 x 980 x 426 = 122043598320
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.
314 : 1, 2, 157, 314
931 : 1, 7, 19, 49, 133, 931
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
426 : 1, 2, 3, 6, 71, 142, 213, 426
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 314,931,980,426, is 1.
Now, the common factors can be found like this.
314:2x 157
931:7x 7x 19
980:2x 2x 5x 7x 7
426:2x 3x 71
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 122043598320/(1x196)
LCM = 122043598320/196
LCM = 622671420
Thus, we can understand that the LCM of 314,931,980,426 is 622671420.
