HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 621, 934, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 621, 934, 66 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 425, 621, 934, 66 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 425, 621, 934, 66 is 1.
HCF(425, 621, 934, 66) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 621, 934, 66 is 1.
Step 1: Since 621 > 425, we apply the division lemma to 621 and 425, to get
621 = 425 x 1 + 196
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 196 and 425, to get
425 = 196 x 2 + 33
Step 3: We consider the new divisor 196 and the new remainder 33, and apply the division lemma to get
196 = 33 x 5 + 31
We consider the new divisor 33 and the new remainder 31,and apply the division lemma to get
33 = 31 x 1 + 2
We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get
31 = 2 x 15 + 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 425 and 621 is 1
Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(33,31) = HCF(196,33) = HCF(425,196) = HCF(621,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 934 > 1, we apply the division lemma to 934 and 1, to get
934 = 1 x 934 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 934 is 1
Notice that 1 = HCF(934,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get
66 = 1 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1
Notice that 1 = HCF(66,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
