HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 607 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 607 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 820, 607 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 820, 607 is 1.
HCF(820, 607) = 1
HCF of 820, 607 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 607 is 1.
Highest Common Factor of 820,607 is 1
Step 1: Since 820 > 607, we apply the division lemma to 820 and 607, to get
820 = 607 x 1 + 213
Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 213 and 607, to get
607 = 213 x 2 + 181
Step 3: We consider the new divisor 213 and the new remainder 181, and apply the division lemma to get
213 = 181 x 1 + 32
We consider the new divisor 181 and the new remainder 32,and apply the division lemma to get
181 = 32 x 5 + 21
We consider the new divisor 32 and the new remainder 21,and apply the division lemma to get
32 = 21 x 1 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 607 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(32,21) = HCF(181,32) = HCF(213,181) = HCF(607,213) = HCF(820,607) .
