HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 498, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 498, 955 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, 498, 955 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, 498, 955 is 1.
HCF(797, 498, 955) = 1
HCF of 797, 498, 955 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, 498, 955 is 1.
Highest Common Factor of 797,498,955 is 1
Step 1: Since 797 > 498, we apply the division lemma to 797 and 498, to get
797 = 498 x 1 + 299
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 299 and 498, to get
498 = 299 x 1 + 199
Step 3: We consider the new divisor 299 and the new remainder 199, and apply the division lemma to get
299 = 199 x 1 + 100
We consider the new divisor 199 and the new remainder 100,and apply the division lemma to get
199 = 100 x 1 + 99
We consider the new divisor 100 and the new remainder 99,and apply the division lemma to get
100 = 99 x 1 + 1
We consider the new divisor 99 and the new remainder 1,and apply the division lemma to get
99 = 1 x 99 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 498 is 1
Notice that 1 = HCF(99,1) = HCF(100,99) = HCF(199,100) = HCF(299,199) = HCF(498,299) = HCF(797,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 955 > 1, we apply the division lemma to 955 and 1, to get
955 = 1 x 955 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 955 is 1
Notice that 1 = HCF(955,1) .
