HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 265, 163, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 265, 163, 668 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 265, 163, 668 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 265, 163, 668 is 1.
HCF(265, 163, 668) = 1
HCF of 265, 163, 668 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 265, 163, 668 is 1.
Highest Common Factor of 265,163,668 is 1
Step 1: Since 265 > 163, we apply the division lemma to 265 and 163, to get
265 = 163 x 1 + 102
Step 2: Since the reminder 163 ≠ 0, we apply division lemma to 102 and 163, to get
163 = 102 x 1 + 61
Step 3: We consider the new divisor 102 and the new remainder 61, and apply the division lemma to get
102 = 61 x 1 + 41
We consider the new divisor 61 and the new remainder 41,and apply the division lemma to get
61 = 41 x 1 + 20
We consider the new divisor 41 and the new remainder 20,and apply the division lemma to get
41 = 20 x 2 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 265 and 163 is 1
Notice that 1 = HCF(20,1) = HCF(41,20) = HCF(61,41) = HCF(102,61) = HCF(163,102) = HCF(265,163) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 668 > 1, we apply the division lemma to 668 and 1, to get
668 = 1 x 668 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 668 is 1
Notice that 1 = HCF(668,1) .
