HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 961, 702, 399, 108 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 961, 702, 399, 108 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 961, 702, 399, 108 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 961, 702, 399, 108 is 1.
HCF(961, 702, 399, 108) = 1
HCF of 961, 702, 399, 108 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 961, 702, 399, 108 is 1.
Highest Common Factor of 961,702,399,108 is 1
Step 1: Since 961 > 702, we apply the division lemma to 961 and 702, to get
961 = 702 x 1 + 259
Step 2: Since the reminder 702 ≠ 0, we apply division lemma to 259 and 702, to get
702 = 259 x 2 + 184
Step 3: We consider the new divisor 259 and the new remainder 184, and apply the division lemma to get
259 = 184 x 1 + 75
We consider the new divisor 184 and the new remainder 75,and apply the division lemma to get
184 = 75 x 2 + 34
We consider the new divisor 75 and the new remainder 34,and apply the division lemma to get
75 = 34 x 2 + 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 961 and 702 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(75,34) = HCF(184,75) = HCF(259,184) = HCF(702,259) = HCF(961,702) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 399 > 1, we apply the division lemma to 399 and 1, to get
399 = 1 x 399 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 399 is 1
Notice that 1 = HCF(399,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 108 > 1, we apply the division lemma to 108 and 1, to get
108 = 1 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 108 is 1
Notice that 1 = HCF(108,1) .
