HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 788, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 788, 613 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 722, 788, 613 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 722, 788, 613 is 1.
HCF(722, 788, 613) = 1
HCF of 722, 788, 613 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 788, 613 is 1.
Highest Common Factor of 722,788,613 is 1
Step 1: Since 788 > 722, we apply the division lemma to 788 and 722, to get
788 = 722 x 1 + 66
Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 66 and 722, to get
722 = 66 x 10 + 62
Step 3: We consider the new divisor 66 and the new remainder 62, and apply the division lemma to get
66 = 62 x 1 + 4
We consider the new divisor 62 and the new remainder 4,and apply the division lemma to get
62 = 4 x 15 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 722 and 788 is 2
Notice that 2 = HCF(4,2) = HCF(62,4) = HCF(66,62) = HCF(722,66) = HCF(788,722) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 613 > 2, we apply the division lemma to 613 and 2, to get
613 = 2 x 306 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 613 is 1
Notice that 1 = HCF(2,1) = HCF(613,2) .
