Find LCM of 775,434,420,757 with Prime Factorization
| 2 | 775, 434, 420, 757 |
| 5 | 775, 217, 210, 757 |
| 7 | 155, 217, 42, 757 |
| 31 | 155, 31, 6, 757 |
| 5, 1, 6, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 31 x 5 x 1 x 6 x 757 = 49280700
Therefore, the lowest common multiple of 775,434,420,757 is 49280700.
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.
775 x 434 x 420 x 757 = 106939119000
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.
775 : 1, 5, 25, 31, 155, 775
434 : 1, 2, 7, 14, 31, 62, 217, 434
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,434,420,757, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
434:2x 7x 31
420:2x 2x 3x 5x 7
757:757
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 31 = 2170
Therefore, the value for common factors is 2170.
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 = 106939119000/(1x2170)
LCM = 106939119000/2170
LCM = 49280700
Thus, we can understand that the LCM of 775,434,420,757 is 49280700.
