Given numbers are 975,989,705,416
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,989,705,416 is 1450269600.
Find LCM of 975,989,705,416 with Prime Factorization
| 3 | 975, 989, 705, 416 |
| 5 | 325, 989, 235, 416 |
| 13 | 65, 989, 47, 416 |
| 5, 989, 47, 32 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 5 x 989 x 47 x 32 = 1450269600
Therefore, the lowest common multiple of 975,989,705,416 is 1450269600.
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.
975 x 989 x 705 x 416 = 282802572000
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
989 : 1, 23, 43, 989
705 : 1, 3, 5, 15, 47, 141, 235, 705
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,989,705,416, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
989:23x 43
705:3x 5x 47
416:2x 2x 2x 2x 2x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13 = 195
Therefore, the value for common factors is 195.
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 = 282802572000/(1x195)
LCM = 282802572000/195
LCM = 1450269600
Thus, we can understand that the LCM of 975,989,705,416 is 1450269600.
