HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 278, 136 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 278, 136 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, 278, 136 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, 278, 136 is 1.
HCF(797, 278, 136) = 1
HCF of 797, 278, 136 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, 278, 136 is 1.
Highest Common Factor of 797,278,136 is 1
Step 1: Since 797 > 278, we apply the division lemma to 797 and 278, to get
797 = 278 x 2 + 241
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 241 and 278, to get
278 = 241 x 1 + 37
Step 3: We consider the new divisor 241 and the new remainder 37, and apply the division lemma to get
241 = 37 x 6 + 19
We consider the new divisor 37 and the new remainder 19,and apply the division lemma to get
37 = 19 x 1 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 278 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(37,19) = HCF(241,37) = HCF(278,241) = HCF(797,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get
136 = 1 x 136 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1
Notice that 1 = HCF(136,1) .
