HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 44, 66, 20, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 44, 66, 20, 425 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 44, 66, 20, 425 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 44, 66, 20, 425 is 1.
HCF(44, 66, 20, 425) = 1
HCF of 44, 66, 20, 425 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 44, 66, 20, 425 is 1.
Highest Common Factor of 44,66,20,425 is 1
Step 1: Since 66 > 44, we apply the division lemma to 66 and 44, to get
66 = 44 x 1 + 22
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 22 and 44, to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 44 and 66 is 22
Notice that 22 = HCF(44,22) = HCF(66,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 20, we apply the division lemma to 22 and 20, to get
22 = 20 x 1 + 2
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 2 and 20, to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 22 and 20 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 425 > 2, we apply the division lemma to 425 and 2, to get
425 = 2 x 212 + 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 425 is 1
Notice that 1 = HCF(2,1) = HCF(425,2) .
