HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 6779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 6779 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, 6779 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, 6779 is 1.
HCF(788, 6779) = 1
HCF of 788, 6779 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, 6779 is 1.
Highest Common Factor of 788,6779 is 1
Step 1: Since 6779 > 788, we apply the division lemma to 6779 and 788, to get
6779 = 788 x 8 + 475
Step 2: Since the reminder 788 ≠ 0, we apply division lemma to 475 and 788, to get
788 = 475 x 1 + 313
Step 3: We consider the new divisor 475 and the new remainder 313, and apply the division lemma to get
475 = 313 x 1 + 162
We consider the new divisor 313 and the new remainder 162,and apply the division lemma to get
313 = 162 x 1 + 151
We consider the new divisor 162 and the new remainder 151,and apply the division lemma to get
162 = 151 x 1 + 11
We consider the new divisor 151 and the new remainder 11,and apply the division lemma to get
151 = 11 x 13 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 788 and 6779 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(151,11) = HCF(162,151) = HCF(313,162) = HCF(475,313) = HCF(788,475) = HCF(6779,788) .
