Given numbers are 770,804,680,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,804,680,748 is 10524360.
Find LCM of 770,804,680,748 with Prime Factorization
| 2 | 770, 804, 680, 748 |
| 2 | 385, 402, 340, 374 |
| 5 | 385, 201, 170, 187 |
| 11 | 77, 201, 34, 187 |
| 17 | 7, 201, 34, 17 |
| 7, 201, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 17 x 7 x 201 x 2 x 1 = 10524360
Therefore, the lowest common multiple of 770,804,680,748 is 10524360.
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.
770 x 804 x 680 x 748 = 314888851200
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,804,680,748, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
804:2x 2x 3x 67
680:2x 2x 2x 5x 17
748:2x 2x 11x 17
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 2x 2x 5x 11x 17 = 14960
Therefore, the value for common factors is 14960.
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 = 314888851200/(2x14960)
LCM = 314888851200/29920
LCM = 10524360
Thus, we can understand that the LCM of 770,804,680,748 is 10524360.
