HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 874, 297, 840 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 874, 297, 840 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 874, 297, 840 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 874, 297, 840 is 1.
HCF(874, 297, 840) = 1
HCF of 874, 297, 840 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 874, 297, 840 is 1.
Highest Common Factor of 874,297,840 is 1
Step 1: Since 874 > 297, we apply the division lemma to 874 and 297, to get
874 = 297 x 2 + 280
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 280 and 297, to get
297 = 280 x 1 + 17
Step 3: We consider the new divisor 280 and the new remainder 17, and apply the division lemma to get
280 = 17 x 16 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 874 and 297 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(280,17) = HCF(297,280) = HCF(874,297) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 840 > 1, we apply the division lemma to 840 and 1, to get
840 = 1 x 840 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 840 is 1
Notice that 1 = HCF(840,1) .
