Given numbers are 787,877,785,988,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,877,785,988,980 is 26229922480580.
Find LCM of 787,877,785,988,980 with Prime Factorization
| 2 | 787, 877, 785, 988, 980 |
| 2 | 787, 877, 785, 494, 490 |
| 5 | 787, 877, 785, 247, 245 |
| 787, 877, 157, 247, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 787 x 877 x 157 x 247 x 49 = 26229922480580
Therefore, the lowest common multiple of 787,877,785,988,980 is 26229922480580.
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.
787 x 877 x 785 x 988 x 980 = 524598449611600
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.
787 : 1, 787
877 : 1, 877
785 : 1, 5, 157, 785
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
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 787,877,785,988,980, is 1.
Now, the common factors can be found like this.
787:787
877:877
785:5x 157
988:2x 2x 13x 19
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 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 524598449611600/(1x20)
LCM = 524598449611600/20
LCM = 26229922480580
Thus, we can understand that the LCM of 787,877,785,988,980 is 26229922480580.
