HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 867, 390, 186, 915 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 867, 390, 186, 915 is 3 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 867, 390, 186, 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 867, 390, 186, 915 is 3.
HCF(867, 390, 186, 915) = 3
HCF of 867, 390, 186, 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 867, 390, 186, 915 is 3.
Highest Common Factor of 867,390,186,915 is 3
Step 1: Since 867 > 390, we apply the division lemma to 867 and 390, to get
867 = 390 x 2 + 87
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 87 and 390, to get
390 = 87 x 4 + 42
Step 3: We consider the new divisor 87 and the new remainder 42, and apply the division lemma to get
87 = 42 x 2 + 3
We consider the new divisor 42 and the new remainder 3, and apply the division lemma to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 867 and 390 is 3
Notice that 3 = HCF(42,3) = HCF(87,42) = HCF(390,87) = HCF(867,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 186 > 3, we apply the division lemma to 186 and 3, to get
186 = 3 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 186 is 3
Notice that 3 = HCF(186,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 915 > 3, we apply the division lemma to 915 and 3, to get
915 = 3 x 305 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 915 is 3
Notice that 3 = HCF(915,3) .
