HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 473, 909, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 542, 473, 909, 211 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 542, 473, 909, 211 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 542, 473, 909, 211 is 1.
HCF(542, 473, 909, 211) = 1
HCF of 542, 473, 909, 211 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 542, 473, 909, 211 is 1.
Highest Common Factor of 542,473,909,211 is 1
Step 1: Since 542 > 473, we apply the division lemma to 542 and 473, to get
542 = 473 x 1 + 69
Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 69 and 473, to get
473 = 69 x 6 + 59
Step 3: We consider the new divisor 69 and the new remainder 59, and apply the division lemma to get
69 = 59 x 1 + 10
We consider the new divisor 59 and the new remainder 10,and apply the division lemma to get
59 = 10 x 5 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 542 and 473 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(59,10) = HCF(69,59) = HCF(473,69) = HCF(542,473) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 1, we apply the division lemma to 909 and 1, to get
909 = 1 x 909 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 909 is 1
Notice that 1 = HCF(909,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 211 > 1, we apply the division lemma to 211 and 1, to get
211 = 1 x 211 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 211 is 1
Notice that 1 = HCF(211,1) .
