HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 536 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 536 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 981, 536 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 981, 536 is 1.
HCF(981, 536) = 1
HCF of 981, 536 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 536 is 1.
Highest Common Factor of 981,536 is 1
Step 1: Since 981 > 536, we apply the division lemma to 981 and 536, to get
981 = 536 x 1 + 445
Step 2: Since the reminder 536 ≠ 0, we apply division lemma to 445 and 536, to get
536 = 445 x 1 + 91
Step 3: We consider the new divisor 445 and the new remainder 91, and apply the division lemma to get
445 = 91 x 4 + 81
We consider the new divisor 91 and the new remainder 81,and apply the division lemma to get
91 = 81 x 1 + 10
We consider the new divisor 81 and the new remainder 10,and apply the division lemma to get
81 = 10 x 8 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 981 and 536 is 1
Notice that 1 = HCF(10,1) = HCF(81,10) = HCF(91,81) = HCF(445,91) = HCF(536,445) = HCF(981,536) .
