HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 954, 43, 166 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 684, 954, 43, 166 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 684, 954, 43, 166 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 684, 954, 43, 166 is 1.
HCF(684, 954, 43, 166) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 684, 954, 43, 166 is 1.
Step 1: Since 954 > 684, we apply the division lemma to 954 and 684, to get
954 = 684 x 1 + 270
Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 270 and 684, to get
684 = 270 x 2 + 144
Step 3: We consider the new divisor 270 and the new remainder 144, and apply the division lemma to get
270 = 144 x 1 + 126
We consider the new divisor 144 and the new remainder 126,and apply the division lemma to get
144 = 126 x 1 + 18
We consider the new divisor 126 and the new remainder 18,and apply the division lemma to get
126 = 18 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 684 and 954 is 18
Notice that 18 = HCF(126,18) = HCF(144,126) = HCF(270,144) = HCF(684,270) = HCF(954,684) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 18, we apply the division lemma to 43 and 18, to get
43 = 18 x 2 + 7
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 7 and 18, to get
18 = 7 x 2 + 4
Step 3: We consider the new divisor 7 and the new remainder 4, and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 18 and 43 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(43,18) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 166 > 1, we apply the division lemma to 166 and 1, to get
166 = 1 x 166 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 166 is 1
Notice that 1 = HCF(166,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
