HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2123, 5665, 19162 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 2123, 5665, 19162 is 11 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 2123, 5665, 19162 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 2123, 5665, 19162 is 11.
HCF(2123, 5665, 19162) = 11
HCF of 2123, 5665, 19162 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2123, 5665, 19162 is 11.
Highest Common Factor of 2123,5665,19162 is 11
Step 1: Since 5665 > 2123, we apply the division lemma to 5665 and 2123, to get
5665 = 2123 x 2 + 1419
Step 2: Since the reminder 2123 ≠ 0, we apply division lemma to 1419 and 2123, to get
2123 = 1419 x 1 + 704
Step 3: We consider the new divisor 1419 and the new remainder 704, and apply the division lemma to get
1419 = 704 x 2 + 11
We consider the new divisor 704 and the new remainder 11, and apply the division lemma to get
704 = 11 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 2123 and 5665 is 11
Notice that 11 = HCF(704,11) = HCF(1419,704) = HCF(2123,1419) = HCF(5665,2123) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19162 > 11, we apply the division lemma to 19162 and 11, to get
19162 = 11 x 1742 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 11 and 19162 is 11
Notice that 11 = HCF(19162,11) .
