HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 34, 22, 89, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 34, 22, 89, 390 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 34, 22, 89, 390 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 34, 22, 89, 390 is 1.
HCF(34, 22, 89, 390) = 1
HCF of 34, 22, 89, 390 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 34, 22, 89, 390 is 1.
Highest Common Factor of 34,22,89,390 is 1
Step 1: Since 34 > 22, we apply the division lemma to 34 and 22, to get
34 = 22 x 1 + 12
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 12 and 22, to get
22 = 12 x 1 + 10
Step 3: We consider the new divisor 12 and the new remainder 10, and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 34 and 22 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 2, we apply the division lemma to 89 and 2, to get
89 = 2 x 44 + 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 89 is 1
Notice that 1 = HCF(2,1) = HCF(89,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get
390 = 1 x 390 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1
Notice that 1 = HCF(390,1) .
