HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 697, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 546, 697, 392 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 546, 697, 392 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, 697, 392 is 1.
HCF(546, 697, 392) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 546, 697, 392 is 1.
Step 1: Since 697 > 546, we apply the division lemma to 697 and 546, to get
697 = 546 x 1 + 151
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 151 and 546, to get
546 = 151 x 3 + 93
Step 3: We consider the new divisor 151 and the new remainder 93, and apply the division lemma to get
151 = 93 x 1 + 58
We consider the new divisor 93 and the new remainder 58,and apply the division lemma to get
93 = 58 x 1 + 35
We consider the new divisor 58 and the new remainder 35,and apply the division lemma to get
58 = 35 x 1 + 23
We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get
35 = 23 x 1 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 546 and 697 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(58,35) = HCF(93,58) = HCF(151,93) = HCF(546,151) = HCF(697,546) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 1, we apply the division lemma to 392 and 1, to get
392 = 1 x 392 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 392 is 1
Notice that 1 = HCF(392,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
