HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 978, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 978, 805 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 673, 978, 805 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 673, 978, 805 is 1.
HCF(673, 978, 805) = 1
HCF of 673, 978, 805 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 673, 978, 805 is 1.
Highest Common Factor of 673,978,805 is 1
Step 1: Since 978 > 673, we apply the division lemma to 978 and 673, to get
978 = 673 x 1 + 305
Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 305 and 673, to get
673 = 305 x 2 + 63
Step 3: We consider the new divisor 305 and the new remainder 63, and apply the division lemma to get
305 = 63 x 4 + 53
We consider the new divisor 63 and the new remainder 53,and apply the division lemma to get
63 = 53 x 1 + 10
We consider the new divisor 53 and the new remainder 10,and apply the division lemma to get
53 = 10 x 5 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 673 and 978 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(53,10) = HCF(63,53) = HCF(305,63) = HCF(673,305) = HCF(978,673) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get
805 = 1 x 805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1
Notice that 1 = HCF(805,1) .
