HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8436, 1019, 73687 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8436, 1019, 73687 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 8436, 1019, 73687 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 8436, 1019, 73687 is 1.
HCF(8436, 1019, 73687) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8436, 1019, 73687 is 1.
Step 1: Since 8436 > 1019, we apply the division lemma to 8436 and 1019, to get
8436 = 1019 x 8 + 284
Step 2: Since the reminder 1019 ≠ 0, we apply division lemma to 284 and 1019, to get
1019 = 284 x 3 + 167
Step 3: We consider the new divisor 284 and the new remainder 167, and apply the division lemma to get
284 = 167 x 1 + 117
We consider the new divisor 167 and the new remainder 117,and apply the division lemma to get
167 = 117 x 1 + 50
We consider the new divisor 117 and the new remainder 50,and apply the division lemma to get
117 = 50 x 2 + 17
We consider the new divisor 50 and the new remainder 17,and apply the division lemma to get
50 = 17 x 2 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8436 and 1019 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(50,17) = HCF(117,50) = HCF(167,117) = HCF(284,167) = HCF(1019,284) = HCF(8436,1019) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 73687 > 1, we apply the division lemma to 73687 and 1, to get
73687 = 1 x 73687 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73687 is 1
Notice that 1 = HCF(73687,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
