HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 397, 387, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 454, 397, 387, 75 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 454, 397, 387, 75 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 454, 397, 387, 75 is 1.
HCF(454, 397, 387, 75) = 1
HCF of 454, 397, 387, 75 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 454, 397, 387, 75 is 1.
Highest Common Factor of 454,397,387,75 is 1
Step 1: Since 454 > 397, we apply the division lemma to 454 and 397, to get
454 = 397 x 1 + 57
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 57 and 397, to get
397 = 57 x 6 + 55
Step 3: We consider the new divisor 57 and the new remainder 55, and apply the division lemma to get
57 = 55 x 1 + 2
We consider the new divisor 55 and the new remainder 2,and apply the division lemma to get
55 = 2 x 27 + 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 454 and 397 is 1
Notice that 1 = HCF(2,1) = HCF(55,2) = HCF(57,55) = HCF(397,57) = HCF(454,397) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 387 > 1, we apply the division lemma to 387 and 1, to get
387 = 1 x 387 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 387 is 1
Notice that 1 = HCF(387,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get
75 = 1 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1
Notice that 1 = HCF(75,1) .
