HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 748, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 844, 748, 163 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 844, 748, 163 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 844, 748, 163 is 1.
HCF(844, 748, 163) = 1
HCF of 844, 748, 163 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 844, 748, 163 is 1.
Highest Common Factor of 844,748,163 is 1
Step 1: Since 844 > 748, we apply the division lemma to 844 and 748, to get
844 = 748 x 1 + 96
Step 2: Since the reminder 748 ≠ 0, we apply division lemma to 96 and 748, to get
748 = 96 x 7 + 76
Step 3: We consider the new divisor 96 and the new remainder 76, and apply the division lemma to get
96 = 76 x 1 + 20
We consider the new divisor 76 and the new remainder 20,and apply the division lemma to get
76 = 20 x 3 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 844 and 748 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(76,20) = HCF(96,76) = HCF(748,96) = HCF(844,748) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 4, we apply the division lemma to 163 and 4, to get
163 = 4 x 40 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 163 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(163,4) .
