HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 935, 620, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 935, 620, 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 935, 620, 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 935, 620, 163 is 1.
HCF(935, 620, 163) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 935, 620, 163 is 1.
Step 1: Since 935 > 620, we apply the division lemma to 935 and 620, to get
935 = 620 x 1 + 315
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 315 and 620, to get
620 = 315 x 1 + 305
Step 3: We consider the new divisor 315 and the new remainder 305, and apply the division lemma to get
315 = 305 x 1 + 10
We consider the new divisor 305 and the new remainder 10,and apply the division lemma to get
305 = 10 x 30 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 935 and 620 is 5
Notice that 5 = HCF(10,5) = HCF(305,10) = HCF(315,305) = HCF(620,315) = HCF(935,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 163 > 5, we apply the division lemma to 163 and 5, to get
163 = 5 x 32 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 5 and 163 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(163,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.
