Given numbers are 807,210,170,710
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,210,170,710 is 68183430.
Find LCM of 807,210,170,710 with Prime Factorization
| 2 | 807, 210, 170, 710 |
| 3 | 807, 105, 85, 355 |
| 5 | 269, 35, 85, 355 |
| 269, 7, 17, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 269 x 7 x 17 x 71 = 68183430
Therefore, the lowest common multiple of 807,210,170,710 is 68183430.
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.
807 x 210 x 170 x 710 = 20455029000
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.
807 : 1, 3, 269, 807
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
170 : 1, 2, 5, 10, 17, 34, 85, 170
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,210,170,710, is 1.
Now, the common factors can be found like this.
807:3x 269
210:2x 3x 5x 7
170:2x 5x 17
710:2x 5x 71
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 = 20455029000/(1x300)
LCM = 20455029000/300
LCM = 68183430
Thus, we can understand that the LCM of 807,210,170,710 is 68183430.
