HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 5112, 9718 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 492, 5112, 9718 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, 5112, 9718 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, 5112, 9718 is 2.
HCF(492, 5112, 9718) = 2
HCF of 492, 5112, 9718 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 492, 5112, 9718 is 2.
Highest Common Factor of 492,5112,9718 is 2
Step 1: Since 5112 > 492, we apply the division lemma to 5112 and 492, to get
5112 = 492 x 10 + 192
Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 192 and 492, to get
492 = 192 x 2 + 108
Step 3: We consider the new divisor 192 and the new remainder 108, and apply the division lemma to get
192 = 108 x 1 + 84
We consider the new divisor 108 and the new remainder 84,and apply the division lemma to get
108 = 84 x 1 + 24
We consider the new divisor 84 and the new remainder 24,and apply the division lemma to get
84 = 24 x 3 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 492 and 5112 is 12
Notice that 12 = HCF(24,12) = HCF(84,24) = HCF(108,84) = HCF(192,108) = HCF(492,192) = HCF(5112,492) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 9718 > 12, we apply the division lemma to 9718 and 12, to get
9718 = 12 x 809 + 10
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 10 and 12, to get
12 = 10 x 1 + 2
Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 12 and 9718 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(9718,12) .
