Find LCM of 161,690,627,570 with Prime Factorization
2 | 161, 690, 627, 570 |
3 | 161, 345, 627, 285 |
5 | 161, 115, 209, 95 |
19 | 161, 23, 209, 19 |
23 | 161, 23, 11, 1 |
7, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 23 x 7 x 1 x 11 x 1 = 1009470
Therefore, the lowest common multiple of 161,690,627,570 is 1009470.
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.
161 x 690 x 627 x 570 = 39702455100
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.
161 : 1, 7, 23, 161
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
627 : 1, 3, 11, 19, 33, 57, 209, 627
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,690,627,570, is 1.
Now, the common factors can be found like this.
161:7x 23
690:2x 3x 5x 23
627:3x 11x 19
570:2x 3x 5x 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 3x 3x 5x 19x 23 = 39330
Therefore, the value for common factors is 39330.
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 = 39702455100/(1x39330)
LCM = 39702455100/39330
LCM = 1009470
Thus, we can understand that the LCM of 161,690,627,570 is 1009470.
