HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 706, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 706, 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 436, 706, 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 436, 706, 163 is 1.
HCF(436, 706, 163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 706, 163 is 1.
Step 1: Since 706 > 436, we apply the division lemma to 706 and 436, to get
706 = 436 x 1 + 270
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 270 and 436, to get
436 = 270 x 1 + 166
Step 3: We consider the new divisor 270 and the new remainder 166, and apply the division lemma to get
270 = 166 x 1 + 104
We consider the new divisor 166 and the new remainder 104,and apply the division lemma to get
166 = 104 x 1 + 62
We consider the new divisor 104 and the new remainder 62,and apply the division lemma to get
104 = 62 x 1 + 42
We consider the new divisor 62 and the new remainder 42,and apply the division lemma to get
62 = 42 x 1 + 20
We consider the new divisor 42 and the new remainder 20,and apply the division lemma to get
42 = 20 x 2 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 436 and 706 is 2
Notice that 2 = HCF(20,2) = HCF(42,20) = HCF(62,42) = HCF(104,62) = HCF(166,104) = HCF(270,166) = HCF(436,270) = HCF(706,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 2, we apply the division lemma to 163 and 2, to get
163 = 2 x 81 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 163 is 1
Notice that 1 = HCF(2,1) = HCF(163,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
