HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 561, 548 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 561, 548 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 434, 561, 548 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 434, 561, 548 is 1.
HCF(434, 561, 548) = 1
HCF of 434, 561, 548 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 434, 561, 548 is 1.
Highest Common Factor of 434,561,548 is 1
Step 1: Since 561 > 434, we apply the division lemma to 561 and 434, to get
561 = 434 x 1 + 127
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 127 and 434, to get
434 = 127 x 3 + 53
Step 3: We consider the new divisor 127 and the new remainder 53, and apply the division lemma to get
127 = 53 x 2 + 21
We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get
53 = 21 x 2 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 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 434 and 561 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(127,53) = HCF(434,127) = HCF(561,434) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 548 > 1, we apply the division lemma to 548 and 1, to get
548 = 1 x 548 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 548 is 1
Notice that 1 = HCF(548,1) .
