Given numbers are 658,74,434

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 658,74,434 is 754726.

Find LCM of 658,74,434 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 7 x 47 x 37 x 31 = 754726

Therefore, the lowest common multiple of 658,74,434 is 754726.

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.

658 x 74 x 434 = 21132328

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

74 : 1, 2, 37, 74

434 : 1, 2, 7, 14, 31, 62, 217, 434

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,74,434, is 2.

Now, the common factors can be found like this.

658:2x 7x 47

74:2x 37

434:2x 7x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 21132328/(2x14)

LCM = 21132328/28

LCM = 754726

Thus, we can understand that the LCM of 658,74,434 is 754726.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 793, 31, 980
• LCM of 682, 10, 246
