HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 83, 28, 42, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 83, 28, 42, 67 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 83, 28, 42, 67 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 83, 28, 42, 67 is 1.
HCF(83, 28, 42, 67) = 1
HCF of 83, 28, 42, 67 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 83, 28, 42, 67 is 1.
Highest Common Factor of 83,28,42,67 is 1
Step 1: Since 83 > 28, we apply the division lemma to 83 and 28, to get
83 = 28 x 2 + 27
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 27 and 28, to get
28 = 27 x 1 + 1
Step 3: We consider the new divisor 27 and the new remainder 1, and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 83 and 28 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(83,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 1, we apply the division lemma to 67 and 1, to get
67 = 1 x 67 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 67 is 1
Notice that 1 = HCF(67,1) .
