Given numbers are 420,269,436,735
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,269,436,735 is 86203740.
Find LCM of 420,269,436,735 with Prime Factorization
| 2 | 420, 269, 436, 735 |
| 2 | 210, 269, 218, 735 |
| 3 | 105, 269, 109, 735 |
| 5 | 35, 269, 109, 245 |
| 7 | 7, 269, 109, 49 |
| 1, 269, 109, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 1 x 269 x 109 x 7 = 86203740
Therefore, the lowest common multiple of 420,269,436,735 is 86203740.
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 269 x 436 x 735 = 36205570800
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
269 : 1, 269
436 : 1, 2, 4, 109, 218, 436
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,269,436,735, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
269:269
436:2x 2x 109
735:3x 5x 7x 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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 36205570800/(1x420)
LCM = 36205570800/420
LCM = 86203740
Thus, we can understand that the LCM of 420,269,436,735 is 86203740.
