Given numbers are 602,490,140,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 602,490,140,445 is 3750460.
Find LCM of 602,490,140,445 with Prime Factorization
| 2 | 602, 490, 140, 445 |
| 5 | 301, 245, 70, 445 |
| 7 | 301, 49, 14, 89 |
| 43, 7, 2, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 43 x 7 x 2 x 89 = 3750460
Therefore, the lowest common multiple of 602,490,140,445 is 3750460.
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.
602 x 490 x 140 x 445 = 18377254000
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.
602 : 1, 2, 7, 14, 43, 86, 301, 602
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 602,490,140,445, is 1.
Now, the common factors can be found like this.
602:2x 7x 43
490:2x 5x 7x 7
140:2x 2x 5x 7
445:5x 89
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 5x 7x 7 = 4900
Therefore, the value for common factors is 4900.
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 = 18377254000/(1x4900)
LCM = 18377254000/4900
LCM = 3750460
Thus, we can understand that the LCM of 602,490,140,445 is 3750460.
