HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 102, 465, 143 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 102, 465, 143 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 210, 102, 465, 143 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 210, 102, 465, 143 is 1.
HCF(210, 102, 465, 143) = 1
HCF of 210, 102, 465, 143 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 102, 465, 143 is 1.
Highest Common Factor of 210,102,465,143 is 1
Step 1: Since 210 > 102, we apply the division lemma to 210 and 102, to get
210 = 102 x 2 + 6
Step 2: Since the reminder 102 ≠ 0, we apply division lemma to 6 and 102, to get
102 = 6 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 210 and 102 is 6
Notice that 6 = HCF(102,6) = HCF(210,102) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 6, we apply the division lemma to 465 and 6, to get
465 = 6 x 77 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 465 is 3
Notice that 3 = HCF(6,3) = HCF(465,6) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 143 > 3, we apply the division lemma to 143 and 3, to get
143 = 3 x 47 + 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 143 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(143,3) .
