HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 387, 852, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 387, 852, 437 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 387, 852, 437 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 387, 852, 437 is 1.
HCF(387, 852, 437) = 1
HCF of 387, 852, 437 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 387, 852, 437 is 1.
Highest Common Factor of 387,852,437 is 1
Step 1: Since 852 > 387, we apply the division lemma to 852 and 387, to get
852 = 387 x 2 + 78
Step 2: Since the reminder 387 ≠ 0, we apply division lemma to 78 and 387, to get
387 = 78 x 4 + 75
Step 3: We consider the new divisor 78 and the new remainder 75, and apply the division lemma to get
78 = 75 x 1 + 3
We consider the new divisor 75 and the new remainder 3, and apply the division lemma to get
75 = 3 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 387 and 852 is 3
Notice that 3 = HCF(75,3) = HCF(78,75) = HCF(387,78) = HCF(852,387) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 437 > 3, we apply the division lemma to 437 and 3, to get
437 = 3 x 145 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 437 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(437,3) .
