Given numbers are 302,690,602,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 302,690,602,805 is 31361190.
Find LCM of 302,690,602,805 with Prime Factorization
| 2 | 302, 690, 602, 805 |
| 5 | 151, 345, 301, 805 |
| 7 | 151, 69, 301, 161 |
| 23 | 151, 69, 43, 23 |
| 151, 3, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 151 x 3 x 43 x 1 = 31361190
Therefore, the lowest common multiple of 302,690,602,805 is 31361190.
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.
302 x 690 x 602 x 805 = 100983031800
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.
302 : 1, 2, 151, 302
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
602 : 1, 2, 7, 14, 43, 86, 301, 602
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,690,602,805, is 1.
Now, the common factors can be found like this.
302:2x 151
690:2x 3x 5x 23
602:2x 7x 43
805:5x 7x 23
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 5x 7x 23 = 3220
Therefore, the value for common factors is 3220.
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 = 100983031800/(1x3220)
LCM = 100983031800/3220
LCM = 31361190
Thus, we can understand that the LCM of 302,690,602,805 is 31361190.
