HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 120, 757, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 120, 757, 211 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 320, 120, 757, 211 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 320, 120, 757, 211 is 1.
HCF(320, 120, 757, 211) = 1
HCF of 320, 120, 757, 211 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 120, 757, 211 is 1.
Highest Common Factor of 320,120,757,211 is 1
Step 1: Since 320 > 120, we apply the division lemma to 320 and 120, to get
320 = 120 x 2 + 80
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 80 and 120, to get
120 = 80 x 1 + 40
Step 3: We consider the new divisor 80 and the new remainder 40, and apply the division lemma to get
80 = 40 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 40, the HCF of 320 and 120 is 40
Notice that 40 = HCF(80,40) = HCF(120,80) = HCF(320,120) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 757 > 40, we apply the division lemma to 757 and 40, to get
757 = 40 x 18 + 37
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 37 and 40, to get
40 = 37 x 1 + 3
Step 3: We consider the new divisor 37 and the new remainder 3, and apply the division lemma to get
37 = 3 x 12 + 1
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 40 and 757 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) = HCF(40,37) = HCF(757,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 211 > 1, we apply the division lemma to 211 and 1, to get
211 = 1 x 211 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 211 is 1
Notice that 1 = HCF(211,1) .
