HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 245, 874 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 245, 874 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, 874 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, 874 is 1.
HCF(245, 874) = 1
HCF of 245, 874 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 245, 874 is 1.
Highest Common Factor of 245,874 is 1
Step 1: Since 874 > 245, we apply the division lemma to 874 and 245, to get
874 = 245 x 3 + 139
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 139 and 245, to get
245 = 139 x 1 + 106
Step 3: We consider the new divisor 139 and the new remainder 106, and apply the division lemma to get
139 = 106 x 1 + 33
We consider the new divisor 106 and the new remainder 33,and apply the division lemma to get
106 = 33 x 3 + 7
We consider the new divisor 33 and the new remainder 7,and apply the division lemma to get
33 = 7 x 4 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 874 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(33,7) = HCF(106,33) = HCF(139,106) = HCF(245,139) = HCF(874,245) .
