HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 161, 7212, 4870 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 161, 7212, 4870 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 161, 7212, 4870 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 161, 7212, 4870 is 1.
HCF(161, 7212, 4870) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 161, 7212, 4870 is 1.
Step 1: Since 7212 > 161, we apply the division lemma to 7212 and 161, to get
7212 = 161 x 44 + 128
Step 2: Since the reminder 161 ≠ 0, we apply division lemma to 128 and 161, to get
161 = 128 x 1 + 33
Step 3: We consider the new divisor 128 and the new remainder 33, and apply the division lemma to get
128 = 33 x 3 + 29
We consider the new divisor 33 and the new remainder 29,and apply the division lemma to get
33 = 29 x 1 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 161 and 7212 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(128,33) = HCF(161,128) = HCF(7212,161) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4870 > 1, we apply the division lemma to 4870 and 1, to get
4870 = 1 x 4870 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4870 is 1
Notice that 1 = HCF(4870,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
