Given numbers are 695,580,120,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 695,580,120,980 is 23702280.
Find LCM of 695,580,120,980 with Prime Factorization
| 2 | 695, 580, 120, 980 |
| 2 | 695, 290, 60, 490 |
| 5 | 695, 145, 30, 245 |
| 139, 29, 6, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 139 x 29 x 6 x 49 = 23702280
Therefore, the lowest common multiple of 695,580,120,980 is 23702280.
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.
695 x 580 x 120 x 980 = 47404560000
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.
695 : 1, 5, 139, 695
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,580,120,980, is 5.
Now, the common factors can be found like this.
695:5x 139
580:2x 2x 5x 29
120:2x 2x 2x 3x 5
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 2x 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 47404560000/(5x400)
LCM = 47404560000/2000
LCM = 23702280
Thus, we can understand that the LCM of 695,580,120,980 is 23702280.
