HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 440, 392, 16 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 125, 440, 392, 16 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 125, 440, 392, 16 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 125, 440, 392, 16 is 1.
HCF(125, 440, 392, 16) = 1
HCF of 125, 440, 392, 16 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 125, 440, 392, 16 is 1.
Highest Common Factor of 125,440,392,16 is 1
Step 1: Since 440 > 125, we apply the division lemma to 440 and 125, to get
440 = 125 x 3 + 65
Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 65 and 125, to get
125 = 65 x 1 + 60
Step 3: We consider the new divisor 65 and the new remainder 60, and apply the division lemma to get
65 = 60 x 1 + 5
We consider the new divisor 60 and the new remainder 5, and apply the division lemma to get
60 = 5 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 125 and 440 is 5
Notice that 5 = HCF(60,5) = HCF(65,60) = HCF(125,65) = HCF(440,125) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 5, we apply the division lemma to 392 and 5, to get
392 = 5 x 78 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 392 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(392,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 16 > 1, we apply the division lemma to 16 and 1, to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 16 is 1
Notice that 1 = HCF(16,1) .
