HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 843 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 843 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 670, 843 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 670, 843 is 1.
HCF(670, 843) = 1
HCF of 670, 843 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 843 is 1.
Highest Common Factor of 670,843 is 1
Step 1: Since 843 > 670, we apply the division lemma to 843 and 670, to get
843 = 670 x 1 + 173
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 173 and 670, to get
670 = 173 x 3 + 151
Step 3: We consider the new divisor 173 and the new remainder 151, and apply the division lemma to get
173 = 151 x 1 + 22
We consider the new divisor 151 and the new remainder 22,and apply the division lemma to get
151 = 22 x 6 + 19
We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get
22 = 19 x 1 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 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 670 and 843 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(151,22) = HCF(173,151) = HCF(670,173) = HCF(843,670) .
