Given numbers are 921,49,749

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

The LCM of 921,49,749 is 4828803.

Find LCM of 921,49,749 with Prime Factorization

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

7 x 921 x 7 x 107 = 4828803

Therefore, the lowest common multiple of 921,49,749 is 4828803.

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.

921 x 49 x 749 = 33801621

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.

921 : 1, 3, 307, 921

49 : 1, 7, 49

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,49,749, is 1.

Now, the common factors can be found like this.

921:3x 307

49:7x 7

749:7x 107

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

7 = 7

Therefore, the value for common factors is 7.

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 = 33801621/(1x7)

LCM = 33801621/7

LCM = 4828803

Thus, we can understand that the LCM of 921,49,749 is 4828803.

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

• LCM of 861, 15, 681
• LCM of 334, 30, 798
