HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 467, 506, 645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 467, 506, 645 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 467, 506, 645 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 467, 506, 645 is 1.
HCF(467, 506, 645) = 1
HCF of 467, 506, 645 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 467, 506, 645 is 1.
Highest Common Factor of 467,506,645 is 1
Step 1: Since 506 > 467, we apply the division lemma to 506 and 467, to get
506 = 467 x 1 + 39
Step 2: Since the reminder 467 ≠ 0, we apply division lemma to 39 and 467, to get
467 = 39 x 11 + 38
Step 3: We consider the new divisor 39 and the new remainder 38, and apply the division lemma to get
39 = 38 x 1 + 1
We consider the new divisor 38 and the new remainder 1, and apply the division lemma to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 467 and 506 is 1
Notice that 1 = HCF(38,1) = HCF(39,38) = HCF(467,39) = HCF(506,467) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 645 > 1, we apply the division lemma to 645 and 1, to get
645 = 1 x 645 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 645 is 1
Notice that 1 = HCF(645,1) .
