Find LCM of 340,744,409,985,770 with Prime Factorization
2 | 340, 744, 409, 985, 770 |
2 | 170, 372, 409, 985, 385 |
5 | 85, 186, 409, 985, 385 |
17, 186, 409, 197, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 186 x 409 x 197 x 77 = 392348612040
Therefore, the lowest common multiple of 340,744,409,985,770 is 392348612040.
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.
340 x 744 x 409 x 985 x 770 = 78469722408000
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
409 : 1, 409
985 : 1, 5, 197, 985
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,744,409,985,770, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
744:2x 2x 2x 3x 31
409:409
985:5x 197
770:2x 5x 7x 11
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 78469722408000/(1x200)
LCM = 78469722408000/200
LCM = 392348612040
Thus, we can understand that the LCM of 340,744,409,985,770 is 392348612040.
