HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 42, 217, 533, 146 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 42, 217, 533, 146 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 42, 217, 533, 146 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 42, 217, 533, 146 is 1.
HCF(42, 217, 533, 146) = 1
HCF of 42, 217, 533, 146 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 42, 217, 533, 146 is 1.
Highest Common Factor of 42,217,533,146 is 1
Step 1: Since 217 > 42, we apply the division lemma to 217 and 42, to get
217 = 42 x 5 + 7
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 7 and 42, to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 42 and 217 is 7
Notice that 7 = HCF(42,7) = HCF(217,42) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 533 > 7, we apply the division lemma to 533 and 7, to get
533 = 7 x 76 + 1
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 1 and 7, to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 533 is 1
Notice that 1 = HCF(7,1) = HCF(533,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 146 > 1, we apply the division lemma to 146 and 1, to get
146 = 1 x 146 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 146 is 1
Notice that 1 = HCF(146,1) .
