HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 865, 427, 632 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 865, 427, 632 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 391, 865, 427, 632 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 391, 865, 427, 632 is 1.
HCF(391, 865, 427, 632) = 1
HCF of 391, 865, 427, 632 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 865, 427, 632 is 1.
Highest Common Factor of 391,865,427,632 is 1
Step 1: Since 865 > 391, we apply the division lemma to 865 and 391, to get
865 = 391 x 2 + 83
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 83 and 391, to get
391 = 83 x 4 + 59
Step 3: We consider the new divisor 83 and the new remainder 59, and apply the division lemma to get
83 = 59 x 1 + 24
We consider the new divisor 59 and the new remainder 24,and apply the division lemma to get
59 = 24 x 2 + 11
We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get
24 = 11 x 2 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 391 and 865 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(59,24) = HCF(83,59) = HCF(391,83) = HCF(865,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 427 > 1, we apply the division lemma to 427 and 1, to get
427 = 1 x 427 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 427 is 1
Notice that 1 = HCF(427,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 632 > 1, we apply the division lemma to 632 and 1, to get
632 = 1 x 632 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 632 is 1
Notice that 1 = HCF(632,1) .
