Given numbers are 972,500,771,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,500,771,175 is 218578500.
Find LCM of 972,500,771,175 with Prime Factorization
| 2 | 972, 500, 771, 175 |
| 2 | 486, 250, 771, 175 |
| 3 | 243, 125, 771, 175 |
| 5 | 81, 125, 257, 175 |
| 5 | 81, 25, 257, 35 |
| 81, 5, 257, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 81 x 5 x 257 x 7 = 218578500
Therefore, the lowest common multiple of 972,500,771,175 is 218578500.
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.
972 x 500 x 771 x 175 = 65573550000
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
771 : 1, 3, 257, 771
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,500,771,175, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
500:2x 2x 5x 5x 5
771:3x 257
175:5x 5x 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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 65573550000/(1x300)
LCM = 65573550000/300
LCM = 218578500
Thus, we can understand that the LCM of 972,500,771,175 is 218578500.
