Given numbers are 690,596,148,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,596,148,420 is 53255580.
Find LCM of 690,596,148,420 with Prime Factorization
2 | 690, 596, 148, 420 |
2 | 345, 298, 74, 210 |
3 | 345, 149, 37, 105 |
5 | 115, 149, 37, 35 |
23, 149, 37, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 149 x 37 x 7 = 53255580
Therefore, the lowest common multiple of 690,596,148,420 is 53255580.
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.
690 x 596 x 148 x 420 = 25562678400
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
596 : 1, 2, 4, 149, 298, 596
148 : 1, 2, 4, 37, 74, 148
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,596,148,420, is 2.
Now, the common factors can be found like this.
690:2x 3x 5x 23
596:2x 2x 149
148:2x 2x 37
420:2x 2x 3x 5x 7
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 25562678400/(2x240)
LCM = 25562678400/480
LCM = 53255580
Thus, we can understand that the LCM of 690,596,148,420 is 53255580.
