HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 297, 454 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 297, 454 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 297, 454 is 1.
HCF(297, 454) = 1
HCF of 297, 454 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 297, 454 is 1.
Highest Common Factor of 297,454 is 1
Step 1: Since 454 > 297, we apply the division lemma to 454 and 297, to get
454 = 297 x 1 + 157
Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 157 and 297, to get
297 = 157 x 1 + 140
Step 3: We consider the new divisor 157 and the new remainder 140, and apply the division lemma to get
157 = 140 x 1 + 17
We consider the new divisor 140 and the new remainder 17,and apply the division lemma to get
140 = 17 x 8 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 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 297 and 454 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(140,17) = HCF(157,140) = HCF(297,157) = HCF(454,297) .
