HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 258, 612, 385 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 258, 612, 385 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 634, 258, 612, 385 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 634, 258, 612, 385 is 1.
HCF(634, 258, 612, 385) = 1
HCF of 634, 258, 612, 385 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 258, 612, 385 is 1.
Highest Common Factor of 634,258,612,385 is 1
Step 1: Since 634 > 258, we apply the division lemma to 634 and 258, to get
634 = 258 x 2 + 118
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 118 and 258, to get
258 = 118 x 2 + 22
Step 3: We consider the new divisor 118 and the new remainder 22, and apply the division lemma to get
118 = 22 x 5 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 634 and 258 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(118,22) = HCF(258,118) = HCF(634,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 612 > 2, we apply the division lemma to 612 and 2, to get
612 = 2 x 306 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 612 is 2
Notice that 2 = HCF(612,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 385 > 2, we apply the division lemma to 385 and 2, to get
385 = 2 x 192 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 385 is 1
Notice that 1 = HCF(2,1) = HCF(385,2) .
