HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 61, 46, 57, 218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 61, 46, 57, 218 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 61, 46, 57, 218 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 61, 46, 57, 218 is 1.
HCF(61, 46, 57, 218) = 1
HCF of 61, 46, 57, 218 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 61, 46, 57, 218 is 1.
Highest Common Factor of 61,46,57,218 is 1
Step 1: Since 61 > 46, we apply the division lemma to 61 and 46, to get
61 = 46 x 1 + 15
Step 2: Since the reminder 46 ≠ 0, we apply division lemma to 15 and 46, to get
46 = 15 x 3 + 1
Step 3: We consider the new divisor 15 and the new remainder 1, and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 61 and 46 is 1
Notice that 1 = HCF(15,1) = HCF(46,15) = HCF(61,46) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get
57 = 1 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1
Notice that 1 = HCF(57,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 218 > 1, we apply the division lemma to 218 and 1, to get
218 = 1 x 218 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 218 is 1
Notice that 1 = HCF(218,1) .
