HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 755, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 755, 72 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 395, 755, 72 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 395, 755, 72 is 1.
HCF(395, 755, 72) = 1
HCF of 395, 755, 72 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 395, 755, 72 is 1.
Highest Common Factor of 395,755,72 is 1
Step 1: Since 755 > 395, we apply the division lemma to 755 and 395, to get
755 = 395 x 1 + 360
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 360 and 395, to get
395 = 360 x 1 + 35
Step 3: We consider the new divisor 360 and the new remainder 35, and apply the division lemma to get
360 = 35 x 10 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 395 and 755 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(360,35) = HCF(395,360) = HCF(755,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 5, we apply the division lemma to 72 and 5, to get
72 = 5 x 14 + 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 72 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(72,5) .
