HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 533, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 533, 981 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 533, 981 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 533, 981 is 1.
HCF(533, 981) = 1
HCF of 533, 981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 533, 981 is 1.
Highest Common Factor of 533,981 is 1
Step 1: Since 981 > 533, we apply the division lemma to 981 and 533, to get
981 = 533 x 1 + 448
Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 448 and 533, to get
533 = 448 x 1 + 85
Step 3: We consider the new divisor 448 and the new remainder 85, and apply the division lemma to get
448 = 85 x 5 + 23
We consider the new divisor 85 and the new remainder 23,and apply the division lemma to get
85 = 23 x 3 + 16
We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get
23 = 16 x 1 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
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 533 and 981 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(85,23) = HCF(448,85) = HCF(533,448) = HCF(981,533) .
