HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 852, 542 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 546, 852, 542 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 546, 852, 542 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 546, 852, 542 is 2.
HCF(546, 852, 542) = 2
HCF of 546, 852, 542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 546, 852, 542 is 2.
Highest Common Factor of 546,852,542 is 2
Step 1: Since 852 > 546, we apply the division lemma to 852 and 546, to get
852 = 546 x 1 + 306
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 306 and 546, to get
546 = 306 x 1 + 240
Step 3: We consider the new divisor 306 and the new remainder 240, and apply the division lemma to get
306 = 240 x 1 + 66
We consider the new divisor 240 and the new remainder 66,and apply the division lemma to get
240 = 66 x 3 + 42
We consider the new divisor 66 and the new remainder 42,and apply the division lemma to get
66 = 42 x 1 + 24
We consider the new divisor 42 and the new remainder 24,and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 546 and 852 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(66,42) = HCF(240,66) = HCF(306,240) = HCF(546,306) = HCF(852,546) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 6, we apply the division lemma to 542 and 6, to get
542 = 6 x 90 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 542 is 2
Notice that 2 = HCF(6,2) = HCF(542,6) .
