The LCM of 770,616,617,971,247 is 455776641320.
Find LCM of 770,616,617,971,247 with Prime Factorization
| 2 | 770, 616, 617, 971, 247 |
| 7 | 385, 308, 617, 971, 247 |
| 11 | 55, 44, 617, 971, 247 |
| 5, 4, 617, 971, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 5 x 4 x 617 x 971 x 247 = 455776641320
Therefore, the lowest common multiple of 770,616,617,971,247 is 455776641320.
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 616 x 617 x 971 x 247 = 70189602763280
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
617 : 1, 617
971 : 1, 971
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,616,617,971,247, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
616:2x 2x 2x 7x 11
617:617
971:971
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 70189602763280/(1x154)
LCM = 70189602763280/154
LCM = 455776641320
Thus, we can understand that the LCM of 770,616,617,971,247 is 455776641320.
