HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 263, 647, 147 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 263, 647, 147 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, 647, 147 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, 647, 147 is 1.
HCF(263, 647, 147) = 1
HCF of 263, 647, 147 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, 647, 147 is 1.
Highest Common Factor of 263,647,147 is 1
Step 1: Since 647 > 263, we apply the division lemma to 647 and 263, to get
647 = 263 x 2 + 121
Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 121 and 263, to get
263 = 121 x 2 + 21
Step 3: We consider the new divisor 121 and the new remainder 21, and apply the division lemma to get
121 = 21 x 5 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 263 and 647 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(121,21) = HCF(263,121) = HCF(647,263) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 147 > 1, we apply the division lemma to 147 and 1, to get
147 = 1 x 147 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 147 is 1
Notice that 1 = HCF(147,1) .
