HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 569, 421, 147 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 569, 421, 147 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 569, 421, 147 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 569, 421, 147 is 1.
HCF(569, 421, 147) = 1
HCF of 569, 421, 147 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 569, 421, 147 is 1.
Highest Common Factor of 569,421,147 is 1
Step 1: Since 569 > 421, we apply the division lemma to 569 and 421, to get
569 = 421 x 1 + 148
Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 148 and 421, to get
421 = 148 x 2 + 125
Step 3: We consider the new divisor 148 and the new remainder 125, and apply the division lemma to get
148 = 125 x 1 + 23
We consider the new divisor 125 and the new remainder 23,and apply the division lemma to get
125 = 23 x 5 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 569 and 421 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(125,23) = HCF(148,125) = HCF(421,148) = HCF(569,421) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 147 > 1, we apply the division lemma to 147 and 1, to get
147 = 1 x 147 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 147 is 1
Notice that 1 = HCF(147,1) .
