Calculate the LCM of 821,262,942,222

Given numbers are 821,262,942,222

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

The LCM of 821,262,942,222 is 3748582554.

Find LCM of 821,262,942,222 with Prime Factorization


2 821, 262, 942, 222
3 821, 131, 471, 111
821, 131, 157, 37

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

2 x 3 x 821 x 131 x 157 x 37 = 3748582554

Therefore, the lowest common multiple of 821,262,942,222 is 3748582554.

LCM Formula to Find Lowest Common Multiple of 821,262,942,222

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.

821 x 262 x 942 x 222 = 44982990648

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.

821 : 1, 821

262 : 1, 2, 131, 262

942 : 1, 2, 3, 6, 157, 314, 471, 942

222 : 1, 2, 3, 6, 37, 74, 111, 222

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,262,942,222, is 1.

Now, the common factors can be found like this.

821:821

262:2x 131

942:2x 3x 157

222:2x 3x 37

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 3 = 12

Therefore, the value for common factors is 12.

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 = 44982990648/(1x12)

LCM = 44982990648/12

LCM = 3748582554

Thus, we can understand that the LCM of 821,262,942,222 is 3748582554.
