Given numbers are 217,210,302,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,210,302,545 is 107148090.
Find LCM of 217,210,302,545 with Prime Factorization
2 | 217, 210, 302, 545 |
5 | 217, 105, 151, 545 |
7 | 217, 21, 151, 109 |
31, 3, 151, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 31 x 3 x 151 x 109 = 107148090
Therefore, the lowest common multiple of 217,210,302,545 is 107148090.
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.
217 x 210 x 302 x 545 = 7500366300
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.
217 : 1, 7, 31, 217
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
302 : 1, 2, 151, 302
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,210,302,545, is 1.
Now, the common factors can be found like this.
217:7x 31
210:2x 3x 5x 7
302:2x 151
545:5x 109
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 7 = 70
Therefore, the value for common factors is 70.
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 = 7500366300/(1x70)
LCM = 7500366300/70
LCM = 107148090
Thus, we can understand that the LCM of 217,210,302,545 is 107148090.
