HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 572, 784, 542, 494 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 572, 784, 542, 494 is 2 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 572, 784, 542, 494 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 572, 784, 542, 494 is 2.
HCF(572, 784, 542, 494) = 2
HCF of 572, 784, 542, 494 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 572, 784, 542, 494 is 2.
Highest Common Factor of 572,784,542,494 is 2
Step 1: Since 784 > 572, we apply the division lemma to 784 and 572, to get
784 = 572 x 1 + 212
Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 212 and 572, to get
572 = 212 x 2 + 148
Step 3: We consider the new divisor 212 and the new remainder 148, and apply the division lemma to get
212 = 148 x 1 + 64
We consider the new divisor 148 and the new remainder 64,and apply the division lemma to get
148 = 64 x 2 + 20
We consider the new divisor 64 and the new remainder 20,and apply the division lemma to get
64 = 20 x 3 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 572 and 784 is 4
Notice that 4 = HCF(20,4) = HCF(64,20) = HCF(148,64) = HCF(212,148) = HCF(572,212) = HCF(784,572) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 4, we apply the division lemma to 542 and 4, to get
542 = 4 x 135 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 542 is 2
Notice that 2 = HCF(4,2) = HCF(542,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 494 > 2, we apply the division lemma to 494 and 2, to get
494 = 2 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 494 is 2
Notice that 2 = HCF(494,2) .
