HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 83, 55, 30, 215 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 83, 55, 30, 215 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, 55, 30, 215 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, 55, 30, 215 is 1.
HCF(83, 55, 30, 215) = 1
HCF of 83, 55, 30, 215 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, 55, 30, 215 is 1.
Highest Common Factor of 83,55,30,215 is 1
Step 1: Since 83 > 55, we apply the division lemma to 83 and 55, to get
83 = 55 x 1 + 28
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 28 and 55, to get
55 = 28 x 1 + 27
Step 3: We consider the new divisor 28 and the new remainder 27, and apply the division lemma to get
28 = 27 x 1 + 1
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 55 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(55,28) = HCF(83,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 1, we apply the division lemma to 30 and 1, to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 30 is 1
Notice that 1 = HCF(30,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 215 > 1, we apply the division lemma to 215 and 1, to get
215 = 1 x 215 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 215 is 1
Notice that 1 = HCF(215,1) .
