HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 695, 195, 722 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 695, 195, 722 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 695, 195, 722 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 695, 195, 722 is 1.
HCF(695, 195, 722) = 1
HCF of 695, 195, 722 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 695, 195, 722 is 1.
Highest Common Factor of 695,195,722 is 1
Step 1: Since 695 > 195, we apply the division lemma to 695 and 195, to get
695 = 195 x 3 + 110
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 110 and 195, to get
195 = 110 x 1 + 85
Step 3: We consider the new divisor 110 and the new remainder 85, and apply the division lemma to get
110 = 85 x 1 + 25
We consider the new divisor 85 and the new remainder 25,and apply the division lemma to get
85 = 25 x 3 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 695 and 195 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(85,25) = HCF(110,85) = HCF(195,110) = HCF(695,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 722 > 5, we apply the division lemma to 722 and 5, to get
722 = 5 x 144 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 722 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(722,5) .
