HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 168, 443, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 168, 443, 968 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 168, 443, 968 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 168, 443, 968 is 1.
HCF(168, 443, 968) = 1
HCF of 168, 443, 968 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 168, 443, 968 is 1.
Highest Common Factor of 168,443,968 is 1
Step 1: Since 443 > 168, we apply the division lemma to 443 and 168, to get
443 = 168 x 2 + 107
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 107 and 168, to get
168 = 107 x 1 + 61
Step 3: We consider the new divisor 107 and the new remainder 61, and apply the division lemma to get
107 = 61 x 1 + 46
We consider the new divisor 61 and the new remainder 46,and apply the division lemma to get
61 = 46 x 1 + 15
We consider the new divisor 46 and the new remainder 15,and apply the division lemma to get
46 = 15 x 3 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 168 and 443 is 1
Notice that 1 = HCF(15,1) = HCF(46,15) = HCF(61,46) = HCF(107,61) = HCF(168,107) = HCF(443,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get
968 = 1 x 968 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1
Notice that 1 = HCF(968,1) .
