HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 302, 532, 987, 30 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 302, 532, 987, 30 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 302, 532, 987, 30 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 302, 532, 987, 30 is 1.
HCF(302, 532, 987, 30) = 1
HCF of 302, 532, 987, 30 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 302, 532, 987, 30 is 1.
Highest Common Factor of 302,532,987,30 is 1
Step 1: Since 532 > 302, we apply the division lemma to 532 and 302, to get
532 = 302 x 1 + 230
Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 230 and 302, to get
302 = 230 x 1 + 72
Step 3: We consider the new divisor 230 and the new remainder 72, and apply the division lemma to get
230 = 72 x 3 + 14
We consider the new divisor 72 and the new remainder 14,and apply the division lemma to get
72 = 14 x 5 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 302 and 532 is 2
Notice that 2 = HCF(14,2) = HCF(72,14) = HCF(230,72) = HCF(302,230) = HCF(532,302) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 987 > 2, we apply the division lemma to 987 and 2, to get
987 = 2 x 493 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 987 is 1
Notice that 1 = HCF(2,1) = HCF(987,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 30 > 1, we apply the division lemma to 30 and 1, to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 30 is 1
Notice that 1 = HCF(30,1) .
