HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 245, 90, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 471, 245, 90, 971 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 471, 245, 90, 971 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 471, 245, 90, 971 is 1.
HCF(471, 245, 90, 971) = 1
HCF of 471, 245, 90, 971 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 471, 245, 90, 971 is 1.
Highest Common Factor of 471,245,90,971 is 1
Step 1: Since 471 > 245, we apply the division lemma to 471 and 245, to get
471 = 245 x 1 + 226
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 226 and 245, to get
245 = 226 x 1 + 19
Step 3: We consider the new divisor 226 and the new remainder 19, and apply the division lemma to get
226 = 19 x 11 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 245 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(226,19) = HCF(245,226) = HCF(471,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get
90 = 1 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1
Notice that 1 = HCF(90,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 1, we apply the division lemma to 971 and 1, to get
971 = 1 x 971 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 971 is 1
Notice that 1 = HCF(971,1) .
