HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 379, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 379, 915 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 379, 915 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 379, 915 is 1.
HCF(379, 915) = 1
HCF of 379, 915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 379, 915 is 1.
Highest Common Factor of 379,915 is 1
Step 1: Since 915 > 379, we apply the division lemma to 915 and 379, to get
915 = 379 x 2 + 157
Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 157 and 379, to get
379 = 157 x 2 + 65
Step 3: We consider the new divisor 157 and the new remainder 65, and apply the division lemma to get
157 = 65 x 2 + 27
We consider the new divisor 65 and the new remainder 27,and apply the division lemma to get
65 = 27 x 2 + 11
We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get
27 = 11 x 2 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 379 and 915 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(65,27) = HCF(157,65) = HCF(379,157) = HCF(915,379) .
