HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 788, 894 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 492, 788, 894 is 2 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 492, 788, 894 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 492, 788, 894 is 2.

HCF(492, 788, 894) = 2

Highest common factor (HCF) of 492, 788, 894 is 2.

Highest Common Factor of 492,788,894 using Euclid's algorithm

Highest Common Factor of 492,788,894 is 2

Step 1: Since 788 > 492, we apply the division lemma to 788 and 492, to get

788 = 492 x 1 + 296

Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 296 and 492, to get

492 = 296 x 1 + 196

Step 3: We consider the new divisor 296 and the new remainder 196, and apply the division lemma to get

296 = 196 x 1 + 100

We consider the new divisor 196 and the new remainder 100,and apply the division lemma to get

196 = 100 x 1 + 96

We consider the new divisor 100 and the new remainder 96,and apply the division lemma to get

100 = 96 x 1 + 4

We consider the new divisor 96 and the new remainder 4,and apply the division lemma to get

96 = 4 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 492 and 788 is 4

Notice that 4 = HCF(96,4) = HCF(100,96) = HCF(196,100) = HCF(296,196) = HCF(492,296) = HCF(788,492) .

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

Step 1: Since 894 > 4, we apply the division lemma to 894 and 4, to get

894 = 4 x 223 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 894 is 2

Notice that 2 = HCF(4,2) = HCF(894,4) .
