Given numbers are 175,101,505,398,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 175,101,505,398,210 is 21103950.
Find LCM of 175,101,505,398,210 with Prime Factorization
| 2 | 175, 101, 505, 398, 210 |
| 5 | 175, 101, 505, 199, 105 |
| 7 | 35, 101, 101, 199, 21 |
| 101 | 5, 101, 101, 199, 3 |
| 5, 1, 1, 199, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 101 x 5 x 1 x 1 x 199 x 3 = 21103950
Therefore, the lowest common multiple of 175,101,505,398,210 is 21103950.
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.
175 x 101 x 505 x 398 x 210 = 746024632500
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.
175 : 1, 5, 7, 25, 35, 175
101 : 1, 101
505 : 1, 5, 101, 505
398 : 1, 2, 199, 398
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 175,101,505,398,210, is 1.
Now, the common factors can be found like this.
175:5x 5x 7
101:101
505:5x 101
398:2x 199
210:2x 3x 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 5x 5x 7x 101 = 35350
Therefore, the value for common factors is 35350.
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 = 746024632500/(1x35350)
LCM = 746024632500/35350
LCM = 21103950
Thus, we can understand that the LCM of 175,101,505,398,210 is 21103950.
