HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 353, 558, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 872, 353, 558, 74 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 872, 353, 558, 74 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 872, 353, 558, 74 is 1.
HCF(872, 353, 558, 74) = 1
HCF of 872, 353, 558, 74 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 872, 353, 558, 74 is 1.
Highest Common Factor of 872,353,558,74 is 1
Step 1: Since 872 > 353, we apply the division lemma to 872 and 353, to get
872 = 353 x 2 + 166
Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 166 and 353, to get
353 = 166 x 2 + 21
Step 3: We consider the new divisor 166 and the new remainder 21, and apply the division lemma to get
166 = 21 x 7 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 872 and 353 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(166,21) = HCF(353,166) = HCF(872,353) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 558 > 1, we apply the division lemma to 558 and 1, to get
558 = 1 x 558 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 558 is 1
Notice that 1 = HCF(558,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get
74 = 1 x 74 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1
Notice that 1 = HCF(74,1) .
