HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 633, 238, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 633, 238, 647 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 633, 238, 647 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 633, 238, 647 is 1.
HCF(633, 238, 647) = 1
HCF of 633, 238, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 633, 238, 647 is 1.
Highest Common Factor of 633,238,647 is 1
Step 1: Since 633 > 238, we apply the division lemma to 633 and 238, to get
633 = 238 x 2 + 157
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 157 and 238, to get
238 = 157 x 1 + 81
Step 3: We consider the new divisor 157 and the new remainder 81, and apply the division lemma to get
157 = 81 x 1 + 76
We consider the new divisor 81 and the new remainder 76,and apply the division lemma to get
81 = 76 x 1 + 5
We consider the new divisor 76 and the new remainder 5,and apply the division lemma to get
76 = 5 x 15 + 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 633 and 238 is 1
Notice that 1 = HCF(5,1) = HCF(76,5) = HCF(81,76) = HCF(157,81) = HCF(238,157) = HCF(633,238) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get
647 = 1 x 647 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1
Notice that 1 = HCF(647,1) .
