Given numbers are 137,774,398,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,774,398,980 is 10339765380.
Find LCM of 137,774,398,980 with Prime Factorization
| 2 | 137, 774, 398, 980 |
| 137, 387, 199, 490 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 387 x 199 x 490 = 10339765380
Therefore, the lowest common multiple of 137,774,398,980 is 10339765380.
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.
137 x 774 x 398 x 980 = 41359061520
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.
137 : 1, 137
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
398 : 1, 2, 199, 398
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,774,398,980, is 1.
Now, the common factors can be found like this.
137:137
774:2x 3x 3x 43
398:2x 199
980:2x 2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 41359061520/(1x4)
LCM = 41359061520/4
LCM = 10339765380
Thus, we can understand that the LCM of 137,774,398,980 is 10339765380.
