HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 607, 425, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 965, 607, 425, 115 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 965, 607, 425, 115 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 965, 607, 425, 115 is 1.
HCF(965, 607, 425, 115) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 965, 607, 425, 115 is 1.
Step 1: Since 965 > 607, we apply the division lemma to 965 and 607, to get
965 = 607 x 1 + 358
Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 358 and 607, to get
607 = 358 x 1 + 249
Step 3: We consider the new divisor 358 and the new remainder 249, and apply the division lemma to get
358 = 249 x 1 + 109
We consider the new divisor 249 and the new remainder 109,and apply the division lemma to get
249 = 109 x 2 + 31
We consider the new divisor 109 and the new remainder 31,and apply the division lemma to get
109 = 31 x 3 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 965 and 607 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(109,31) = HCF(249,109) = HCF(358,249) = HCF(607,358) = HCF(965,607) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 1, we apply the division lemma to 425 and 1, to get
425 = 1 x 425 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 425 is 1
Notice that 1 = HCF(425,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 115 > 1, we apply the division lemma to 115 and 1, to get
115 = 1 x 115 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 115 is 1
Notice that 1 = HCF(115,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
