Calculate the LCM of 297,670,971,690

Given numbers are 297,670,971,690

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

The LCM of 297,670,971,690 is 4444043670.

Find LCM of 297,670,971,690 with Prime Factorization


2 297, 670, 971, 690
3 297, 335, 971, 345
5 99, 335, 971, 115
99, 67, 971, 23

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

2 x 3 x 5 x 99 x 67 x 971 x 23 = 4444043670

Therefore, the lowest common multiple of 297,670,971,690 is 4444043670.

LCM Formula to Find Lowest Common Multiple of 297,670,971,690

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.

297 x 670 x 971 x 690 = 133321310100

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

670 : 1, 2, 5, 10, 67, 134, 335, 670

971 : 1, 971

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,670,971,690, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

670:2x 5x 67

971:971

690:2x 3x 5x 23

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 133321310100/(1x30)

LCM = 133321310100/30

LCM = 4444043670

Thus, we can understand that the LCM of 297,670,971,690 is 4444043670.
