HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 559, 661, 981, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 559, 661, 981, 43 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 559, 661, 981, 43 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 559, 661, 981, 43 is 1.
HCF(559, 661, 981, 43) = 1
HCF of 559, 661, 981, 43 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 559, 661, 981, 43 is 1.
Highest Common Factor of 559,661,981,43 is 1
Step 1: Since 661 > 559, we apply the division lemma to 661 and 559, to get
661 = 559 x 1 + 102
Step 2: Since the reminder 559 ≠ 0, we apply division lemma to 102 and 559, to get
559 = 102 x 5 + 49
Step 3: We consider the new divisor 102 and the new remainder 49, and apply the division lemma to get
102 = 49 x 2 + 4
We consider the new divisor 49 and the new remainder 4,and apply the division lemma to get
49 = 4 x 12 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 559 and 661 is 1
Notice that 1 = HCF(4,1) = HCF(49,4) = HCF(102,49) = HCF(559,102) = HCF(661,559) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get
981 = 1 x 981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1
Notice that 1 = HCF(981,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 1, we apply the division lemma to 43 and 1, to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 43 is 1
Notice that 1 = HCF(43,1) .
