HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 1654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 1654 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, 1654 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, 1654 is 1.
HCF(673, 1654) = 1
HCF of 673, 1654 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, 1654 is 1.
Highest Common Factor of 673,1654 is 1
Step 1: Since 1654 > 673, we apply the division lemma to 1654 and 673, to get
1654 = 673 x 2 + 308
Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 308 and 673, to get
673 = 308 x 2 + 57
Step 3: We consider the new divisor 308 and the new remainder 57, and apply the division lemma to get
308 = 57 x 5 + 23
We consider the new divisor 57 and the new remainder 23,and apply the division lemma to get
57 = 23 x 2 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 1654 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(57,23) = HCF(308,57) = HCF(673,308) = HCF(1654,673) .
