Given numbers are 487,319,130,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,319,130,980 is 1979197220.
Find LCM of 487,319,130,980 with Prime Factorization
| 2 | 487, 319, 130, 980 |
| 5 | 487, 319, 65, 490 |
| 487, 319, 13, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 487 x 319 x 13 x 98 = 1979197220
Therefore, the lowest common multiple of 487,319,130,980 is 1979197220.
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.
487 x 319 x 130 x 980 = 19791972200
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.
487 : 1, 487
319 : 1, 11, 29, 319
130 : 1, 2, 5, 10, 13, 26, 65, 130
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 487,319,130,980, is 1.
Now, the common factors can be found like this.
487:487
319:11x 29
130:2x 5x 13
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 5 = 10
Therefore, the value for common factors is 10.
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 = 19791972200/(1x10)
LCM = 19791972200/10
LCM = 1979197220
Thus, we can understand that the LCM of 487,319,130,980 is 1979197220.
