HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 639, 484 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 871, 639, 484 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 871, 639, 484 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 871, 639, 484 is 1.
HCF(871, 639, 484) = 1
HCF of 871, 639, 484 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 871, 639, 484 is 1.
Highest Common Factor of 871,639,484 is 1
Step 1: Since 871 > 639, we apply the division lemma to 871 and 639, to get
871 = 639 x 1 + 232
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 232 and 639, to get
639 = 232 x 2 + 175
Step 3: We consider the new divisor 232 and the new remainder 175, and apply the division lemma to get
232 = 175 x 1 + 57
We consider the new divisor 175 and the new remainder 57,and apply the division lemma to get
175 = 57 x 3 + 4
We consider the new divisor 57 and the new remainder 4,and apply the division lemma to get
57 = 4 x 14 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 639 is 1
Notice that 1 = HCF(4,1) = HCF(57,4) = HCF(175,57) = HCF(232,175) = HCF(639,232) = HCF(871,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 484 > 1, we apply the division lemma to 484 and 1, to get
484 = 1 x 484 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 484 is 1
Notice that 1 = HCF(484,1) .
