HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 993, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 993, 623 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 788, 993, 623 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 788, 993, 623 is 1.
HCF(788, 993, 623) = 1
HCF of 788, 993, 623 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 993, 623 is 1.
Highest Common Factor of 788,993,623 is 1
Step 1: Since 993 > 788, we apply the division lemma to 993 and 788, to get
993 = 788 x 1 + 205
Step 2: Since the reminder 788 ≠ 0, we apply division lemma to 205 and 788, to get
788 = 205 x 3 + 173
Step 3: We consider the new divisor 205 and the new remainder 173, and apply the division lemma to get
205 = 173 x 1 + 32
We consider the new divisor 173 and the new remainder 32,and apply the division lemma to get
173 = 32 x 5 + 13
We consider the new divisor 32 and the new remainder 13,and apply the division lemma to get
32 = 13 x 2 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 788 and 993 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(32,13) = HCF(173,32) = HCF(205,173) = HCF(788,205) = HCF(993,788) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 623 > 1, we apply the division lemma to 623 and 1, to get
623 = 1 x 623 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 623 is 1
Notice that 1 = HCF(623,1) .
