Given numbers are 777,817,168,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,817,168,651 is 157432632.
Find LCM of 777,817,168,651 with Prime Factorization
3 | 777, 817, 168, 651 |
7 | 259, 817, 56, 217 |
37, 817, 8, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 37 x 817 x 8 x 31 = 157432632
Therefore, the lowest common multiple of 777,817,168,651 is 157432632.
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.
777 x 817 x 168 x 651 = 69427790712
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
817 : 1, 19, 43, 817
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,817,168,651, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
817:19x 43
168:2x 2x 2x 3x 7
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 7 = 441
Therefore, the value for common factors is 441.
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 = 69427790712/(1x441)
LCM = 69427790712/441
LCM = 157432632
Thus, we can understand that the LCM of 777,817,168,651 is 157432632.
