Find LCM of 770,425,867,390,188 with Prime Factorization
| 2 | 770, 425, 867, 390, 188 |
| 3 | 385, 425, 867, 195, 94 |
| 5 | 385, 425, 289, 65, 94 |
| 17 | 77, 85, 289, 13, 94 |
| 77, 5, 17, 13, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 77 x 5 x 17 x 13 x 94 = 4078974900
Therefore, the lowest common multiple of 770,425,867,390,188 is 4078974900.
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 425 x 867 x 390 x 188 = 20802771990000
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
425 : 1, 5, 17, 25, 85, 425
867 : 1, 3, 17, 51, 289, 867
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,425,867,390,188, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
425:5x 5x 17
867:3x 17x 17
390:2x 3x 5x 13
188:2x 2x 47
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 3x 5x 5x 17 = 5100
Therefore, the value for common factors is 5100.
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 = 20802771990000/(1x5100)
LCM = 20802771990000/5100
LCM = 4078974900
Thus, we can understand that the LCM of 770,425,867,390,188 is 4078974900.
