Given numbers are 980,746,991,210,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,746,991,210,869 is 944386114980.
Find LCM of 980,746,991,210,869 with Prime Factorization
| 2 | 980, 746, 991, 210, 869 |
| 5 | 490, 373, 991, 105, 869 |
| 7 | 98, 373, 991, 21, 869 |
| 14, 373, 991, 3, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 14 x 373 x 991 x 3 x 869 = 944386114980
Therefore, the lowest common multiple of 980,746,991,210,869 is 944386114980.
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.
980 x 746 x 991 x 210 x 869 = 132214056097200
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
746 : 1, 2, 373, 746
991 : 1, 991
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,746,991,210,869, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
746:2x 373
991:991
210:2x 3x 5x 7
869:11x 79
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 7 = 140
Therefore, the value for common factors is 140.
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 = 132214056097200/(1x140)
LCM = 132214056097200/140
LCM = 944386114980
Thus, we can understand that the LCM of 980,746,991,210,869 is 944386114980.
