Given numbers are 397,700,397,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,700,397,770 is 3056900.
Find LCM of 397,700,397,770 with Prime Factorization
| 2 | 397, 700, 397, 770 |
| 5 | 397, 350, 397, 385 |
| 7 | 397, 70, 397, 77 |
| 397 | 397, 10, 397, 11 |
| 1, 10, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 397 x 1 x 10 x 1 x 11 = 3056900
Therefore, the lowest common multiple of 397,700,397,770 is 3056900.
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.
397 x 700 x 397 x 770 = 84951251000
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.
397 : 1, 397
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
397 : 1, 397
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,700,397,770, is 1.
Now, the common factors can be found like this.
397:397
700:2x 2x 5x 5x 7
397:397
770:2x 5x 7x 11
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 7x 397 = 27790
Therefore, the value for common factors is 27790.
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 = 84951251000/(1x27790)
LCM = 84951251000/27790
LCM = 3056900
Thus, we can understand that the LCM of 397,700,397,770 is 3056900.
