HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 748, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 748, 209 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, 748, 209 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, 748, 209 is 1.
HCF(673, 748, 209) = 1
HCF of 673, 748, 209 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, 748, 209 is 1.
Highest Common Factor of 673,748,209 is 1
Step 1: Since 748 > 673, we apply the division lemma to 748 and 673, to get
748 = 673 x 1 + 75
Step 2: Since the reminder 673 ≠ 0, we apply division lemma to 75 and 673, to get
673 = 75 x 8 + 73
Step 3: We consider the new divisor 75 and the new remainder 73, and apply the division lemma to get
75 = 73 x 1 + 2
We consider the new divisor 73 and the new remainder 2,and apply the division lemma to get
73 = 2 x 36 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 748 is 1
Notice that 1 = HCF(2,1) = HCF(73,2) = HCF(75,73) = HCF(673,75) = HCF(748,673) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 209 > 1, we apply the division lemma to 209 and 1, to get
209 = 1 x 209 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 209 is 1
Notice that 1 = HCF(209,1) .
