HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 793, 628 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 793, 628 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 793, 628 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 793, 628 is 1.
HCF(793, 628) = 1
HCF of 793, 628 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 793, 628 is 1.
Highest Common Factor of 793,628 is 1
Step 1: Since 793 > 628, we apply the division lemma to 793 and 628, to get
793 = 628 x 1 + 165
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 165 and 628, to get
628 = 165 x 3 + 133
Step 3: We consider the new divisor 165 and the new remainder 133, and apply the division lemma to get
165 = 133 x 1 + 32
We consider the new divisor 133 and the new remainder 32,and apply the division lemma to get
133 = 32 x 4 + 5
We consider the new divisor 32 and the new remainder 5,and apply the division lemma to get
32 = 5 x 6 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 793 and 628 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(32,5) = HCF(133,32) = HCF(165,133) = HCF(628,165) = HCF(793,628) .
