HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 545, 553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 545, 553 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, 545, 553 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, 545, 553 is 1.
HCF(981, 545, 553) = 1
HCF of 981, 545, 553 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, 545, 553 is 1.
Highest Common Factor of 981,545,553 is 1
Step 1: Since 981 > 545, we apply the division lemma to 981 and 545, to get
981 = 545 x 1 + 436
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 436 and 545, to get
545 = 436 x 1 + 109
Step 3: We consider the new divisor 436 and the new remainder 109, and apply the division lemma to get
436 = 109 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 109, the HCF of 981 and 545 is 109
Notice that 109 = HCF(436,109) = HCF(545,436) = HCF(981,545) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 553 > 109, we apply the division lemma to 553 and 109, to get
553 = 109 x 5 + 8
Step 2: Since the reminder 109 ≠ 0, we apply division lemma to 8 and 109, to get
109 = 8 x 13 + 5
Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 109 and 553 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(109,8) = HCF(553,109) .
