HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 21, 33, 527, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 21, 33, 527, 889 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 21, 33, 527, 889 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 21, 33, 527, 889 is 1.
HCF(21, 33, 527, 889) = 1
HCF of 21, 33, 527, 889 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 21, 33, 527, 889 is 1.
Highest Common Factor of 21,33,527,889 is 1
Step 1: Since 33 > 21, we apply the division lemma to 33 and 21, to get
33 = 21 x 1 + 12
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 12 and 21, to get
21 = 12 x 1 + 9
Step 3: We consider the new divisor 12 and the new remainder 9, and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 21 and 33 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(33,21) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 527 > 3, we apply the division lemma to 527 and 3, to get
527 = 3 x 175 + 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 527 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(527,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 1, we apply the division lemma to 889 and 1, to get
889 = 1 x 889 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 889 is 1
Notice that 1 = HCF(889,1) .
