HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 245, 46 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 245, 46 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 427, 245, 46 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 427, 245, 46 is 1.
HCF(427, 245, 46) = 1
HCF of 427, 245, 46 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 245, 46 is 1.
Highest Common Factor of 427,245,46 is 1
Step 1: Since 427 > 245, we apply the division lemma to 427 and 245, to get
427 = 245 x 1 + 182
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 182 and 245, to get
245 = 182 x 1 + 63
Step 3: We consider the new divisor 182 and the new remainder 63, and apply the division lemma to get
182 = 63 x 2 + 56
We consider the new divisor 63 and the new remainder 56,and apply the division lemma to get
63 = 56 x 1 + 7
We consider the new divisor 56 and the new remainder 7,and apply the division lemma to get
56 = 7 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 427 and 245 is 7
Notice that 7 = HCF(56,7) = HCF(63,56) = HCF(182,63) = HCF(245,182) = HCF(427,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 46 > 7, we apply the division lemma to 46 and 7, to get
46 = 7 x 6 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 46 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(46,7) .
