HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 642, 784, 268 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 923, 642, 784, 268 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 923, 642, 784, 268 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 923, 642, 784, 268 is 1.

HCF(923, 642, 784, 268) = 1

Highest Common Factor of 923,642,784,268 using Euclid's algorithm

Highest Common Factor of 923,642,784,268 is 1

Step 1: Since 923 > 642, we apply the division lemma to 923 and 642, to get

923 = 642 x 1 + 281

Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 281 and 642, to get

642 = 281 x 2 + 80

Step 3: We consider the new divisor 281 and the new remainder 80, and apply the division lemma to get

281 = 80 x 3 + 41

We consider the new divisor 80 and the new remainder 41,and apply the division lemma to get

80 = 41 x 1 + 39

We consider the new divisor 41 and the new remainder 39,and apply the division lemma to get

41 = 39 x 1 + 2

We consider the new divisor 39 and the new remainder 2,and apply the division lemma to get

39 = 2 x 19 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 642 is 1

Notice that 1 = HCF(2,1) = HCF(39,2) = HCF(41,39) = HCF(80,41) = HCF(281,80) = HCF(642,281) = HCF(923,642) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 784 > 1, we apply the division lemma to 784 and 1, to get

784 = 1 x 784 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 784 is 1

Notice that 1 = HCF(784,1) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 268 > 1, we apply the division lemma to 268 and 1, to get

268 = 1 x 268 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 268 is 1

Notice that 1 = HCF(268,1) .
