HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 688, 603 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 688, 603 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 797, 688, 603 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 797, 688, 603 is 1.
HCF(797, 688, 603) = 1
HCF of 797, 688, 603 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 688, 603 is 1.
Highest Common Factor of 797,688,603 is 1
Step 1: Since 797 > 688, we apply the division lemma to 797 and 688, to get
797 = 688 x 1 + 109
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 109 and 688, to get
688 = 109 x 6 + 34
Step 3: We consider the new divisor 109 and the new remainder 34, and apply the division lemma to get
109 = 34 x 3 + 7
We consider the new divisor 34 and the new remainder 7,and apply the division lemma to get
34 = 7 x 4 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 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 797 and 688 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(109,34) = HCF(688,109) = HCF(797,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 603 > 1, we apply the division lemma to 603 and 1, to get
603 = 1 x 603 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 603 is 1
Notice that 1 = HCF(603,1) .
