Given numbers are 420,478,535,829,340
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,478,535,829,340 is 151368121380.
Find LCM of 420,478,535,829,340 with Prime Factorization
2 | 420, 478, 535, 829, 340 |
2 | 210, 239, 535, 829, 170 |
5 | 105, 239, 535, 829, 85 |
21, 239, 107, 829, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 21 x 239 x 107 x 829 x 17 = 151368121380
Therefore, the lowest common multiple of 420,478,535,829,340 is 151368121380.
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.
420 x 478 x 535 x 829 x 340 = 30273624276000
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.
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
478 : 1, 2, 239, 478
535 : 1, 5, 107, 535
829 : 1, 829
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,478,535,829,340, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
478:2x 239
535:5x 107
829:829
340:2x 2x 5x 17
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 = 30273624276000/(1x200)
LCM = 30273624276000/200
LCM = 151368121380
Thus, we can understand that the LCM of 420,478,535,829,340 is 151368121380.
