HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 263, 499, 151, 638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 263, 499, 151, 638 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 263, 499, 151, 638 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 263, 499, 151, 638 is 1.
HCF(263, 499, 151, 638) = 1
HCF of 263, 499, 151, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 263, 499, 151, 638 is 1.
Highest Common Factor of 263,499,151,638 is 1
Step 1: Since 499 > 263, we apply the division lemma to 499 and 263, to get
499 = 263 x 1 + 236
Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 236 and 263, to get
263 = 236 x 1 + 27
Step 3: We consider the new divisor 236 and the new remainder 27, and apply the division lemma to get
236 = 27 x 8 + 20
We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get
27 = 20 x 1 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 263 and 499 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(236,27) = HCF(263,236) = HCF(499,263) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get
151 = 1 x 151 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1
Notice that 1 = HCF(151,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 638 > 1, we apply the division lemma to 638 and 1, to get
638 = 1 x 638 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 638 is 1
Notice that 1 = HCF(638,1) .
