HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 245, 735, 971, 882 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 245, 735, 971, 882 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 245, 735, 971, 882 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 245, 735, 971, 882 is 1.
HCF(245, 735, 971, 882) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 245, 735, 971, 882 is 1.
Step 1: Since 735 > 245, we apply the division lemma to 735 and 245, to get
735 = 245 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 245, the HCF of 245 and 735 is 245
Notice that 245 = HCF(735,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 245, we apply the division lemma to 971 and 245, to get
971 = 245 x 3 + 236
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 236 and 245, to get
245 = 236 x 1 + 9
Step 3: We consider the new divisor 236 and the new remainder 9, and apply the division lemma to get
236 = 9 x 26 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 245 and 971 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(236,9) = HCF(245,236) = HCF(971,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 882 > 1, we apply the division lemma to 882 and 1, to get
882 = 1 x 882 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 882 is 1
Notice that 1 = HCF(882,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
