HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 734, 397, 36 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 468, 734, 397, 36 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 468, 734, 397, 36 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 468, 734, 397, 36 is 1.
HCF(468, 734, 397, 36) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 468, 734, 397, 36 is 1.
Step 1: Since 734 > 468, we apply the division lemma to 734 and 468, to get
734 = 468 x 1 + 266
Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 266 and 468, to get
468 = 266 x 1 + 202
Step 3: We consider the new divisor 266 and the new remainder 202, and apply the division lemma to get
266 = 202 x 1 + 64
We consider the new divisor 202 and the new remainder 64,and apply the division lemma to get
202 = 64 x 3 + 10
We consider the new divisor 64 and the new remainder 10,and apply the division lemma to get
64 = 10 x 6 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 468 and 734 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(64,10) = HCF(202,64) = HCF(266,202) = HCF(468,266) = HCF(734,468) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 397 > 2, we apply the division lemma to 397 and 2, to get
397 = 2 x 198 + 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 397 is 1
Notice that 1 = HCF(2,1) = HCF(397,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 36 > 1, we apply the division lemma to 36 and 1, to get
36 = 1 x 36 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 36 is 1
Notice that 1 = HCF(36,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
