HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 373, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 373, 689 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 373, 689 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 373, 689 is 1.
HCF(373, 689) = 1
HCF of 373, 689 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 373, 689 is 1.
Highest Common Factor of 373,689 is 1
Step 1: Since 689 > 373, we apply the division lemma to 689 and 373, to get
689 = 373 x 1 + 316
Step 2: Since the reminder 373 ≠ 0, we apply division lemma to 316 and 373, to get
373 = 316 x 1 + 57
Step 3: We consider the new divisor 316 and the new remainder 57, and apply the division lemma to get
316 = 57 x 5 + 31
We consider the new divisor 57 and the new remainder 31,and apply the division lemma to get
57 = 31 x 1 + 26
We consider the new divisor 31 and the new remainder 26,and apply the division lemma to get
31 = 26 x 1 + 5
We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get
26 = 5 x 5 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 373 and 689 is 1
Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(31,26) = HCF(57,31) = HCF(316,57) = HCF(373,316) = HCF(689,373) .
