HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 889, 487, 612 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 889, 487, 612 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 889, 487, 612 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 889, 487, 612 is 1.
HCF(889, 487, 612) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 889, 487, 612 is 1.
Step 1: Since 889 > 487, we apply the division lemma to 889 and 487, to get
889 = 487 x 1 + 402
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 402 and 487, to get
487 = 402 x 1 + 85
Step 3: We consider the new divisor 402 and the new remainder 85, and apply the division lemma to get
402 = 85 x 4 + 62
We consider the new divisor 85 and the new remainder 62,and apply the division lemma to get
85 = 62 x 1 + 23
We consider the new divisor 62 and the new remainder 23,and apply the division lemma to get
62 = 23 x 2 + 16
We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get
23 = 16 x 1 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 889 and 487 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(62,23) = HCF(85,62) = HCF(402,85) = HCF(487,402) = HCF(889,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 612 > 1, we apply the division lemma to 612 and 1, to get
612 = 1 x 612 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 612 is 1
Notice that 1 = HCF(612,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
