HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 122, 959 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 122, 959 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 715, 122, 959 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 715, 122, 959 is 1.
HCF(715, 122, 959) = 1
HCF of 715, 122, 959 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 122, 959 is 1.
Highest Common Factor of 715,122,959 is 1
Step 1: Since 715 > 122, we apply the division lemma to 715 and 122, to get
715 = 122 x 5 + 105
Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 105 and 122, to get
122 = 105 x 1 + 17
Step 3: We consider the new divisor 105 and the new remainder 17, and apply the division lemma to get
105 = 17 x 6 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 715 and 122 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(105,17) = HCF(122,105) = HCF(715,122) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 959 > 1, we apply the division lemma to 959 and 1, to get
959 = 1 x 959 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 959 is 1
Notice that 1 = HCF(959,1) .
