HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 292, 117 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 492, 292, 117 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 492, 292, 117 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, 292, 117 is 1.

HCF(492, 292, 117) = 1

Highest common factor (HCF) of 492, 292, 117 is 1.

Highest Common Factor of 492,292,117 using Euclid's algorithm

Highest Common Factor of 492,292,117 is 1

Step 1: Since 492 > 292, we apply the division lemma to 492 and 292, to get

492 = 292 x 1 + 200

Step 2: Since the reminder 292 ≠ 0, we apply division lemma to 200 and 292, to get

292 = 200 x 1 + 92

Step 3: We consider the new divisor 200 and the new remainder 92, and apply the division lemma to get

200 = 92 x 2 + 16

We consider the new divisor 92 and the new remainder 16,and apply the division lemma to get

92 = 16 x 5 + 12

We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get

16 = 12 x 1 + 4

We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get

12 = 4 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 492 and 292 is 4

Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(92,16) = HCF(200,92) = HCF(292,200) = HCF(492,292) .

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

Step 1: Since 117 > 4, we apply the division lemma to 117 and 4, to get

117 = 4 x 29 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 117 is 1

Notice that 1 = HCF(4,1) = HCF(117,4) .
