Find LCM of 868,493,777,278,139 with Prime Factorization
| 2 | 868, 493, 777, 278, 139 |
| 7 | 434, 493, 777, 139, 139 |
| 139 | 62, 493, 111, 139, 139 |
| 62, 493, 111, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 139 x 62 x 493 x 111 x 1 x 1 = 6602439396
Therefore, the lowest common multiple of 868,493,777,278,139 is 6602439396.
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.
868 x 493 x 777 x 278 x 139 = 12848347064616
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
493 : 1, 17, 29, 493
777 : 1, 3, 7, 21, 37, 111, 259, 777
278 : 1, 2, 139, 278
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,493,777,278,139, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
493:17x 29
777:3x 7x 37
278:2x 139
139:139
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 139 = 1946
Therefore, the value for common factors is 1946.
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 = 12848347064616/(1x1946)
LCM = 12848347064616/1946
LCM = 6602439396
Thus, we can understand that the LCM of 868,493,777,278,139 is 6602439396.
