HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 936, 546, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 936, 546, 25 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 936, 546, 25 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 936, 546, 25 is 1.
HCF(936, 546, 25) = 1
HCF of 936, 546, 25 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 936, 546, 25 is 1.
Highest Common Factor of 936,546,25 is 1
Step 1: Since 936 > 546, we apply the division lemma to 936 and 546, to get
936 = 546 x 1 + 390
Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 390 and 546, to get
546 = 390 x 1 + 156
Step 3: We consider the new divisor 390 and the new remainder 156, and apply the division lemma to get
390 = 156 x 2 + 78
We consider the new divisor 156 and the new remainder 78, and apply the division lemma to get
156 = 78 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 78, the HCF of 936 and 546 is 78
Notice that 78 = HCF(156,78) = HCF(390,156) = HCF(546,390) = HCF(936,546) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 25, we apply the division lemma to 78 and 25, to get
78 = 25 x 3 + 3
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 3 and 25, to get
25 = 3 x 8 + 1
Step 3: 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 78 and 25 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(78,25) .
