HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 915, 732, 339 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 915, 732, 339 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 655, 915, 732, 339 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 655, 915, 732, 339 is 1.
HCF(655, 915, 732, 339) = 1
HCF of 655, 915, 732, 339 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 655, 915, 732, 339 is 1.
Highest Common Factor of 655,915,732,339 is 1
Step 1: Since 915 > 655, we apply the division lemma to 915 and 655, to get
915 = 655 x 1 + 260
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 260 and 655, to get
655 = 260 x 2 + 135
Step 3: We consider the new divisor 260 and the new remainder 135, and apply the division lemma to get
260 = 135 x 1 + 125
We consider the new divisor 135 and the new remainder 125,and apply the division lemma to get
135 = 125 x 1 + 10
We consider the new divisor 125 and the new remainder 10,and apply the division lemma to get
125 = 10 x 12 + 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 655 and 915 is 5
Notice that 5 = HCF(10,5) = HCF(125,10) = HCF(135,125) = HCF(260,135) = HCF(655,260) = HCF(915,655) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 732 > 5, we apply the division lemma to 732 and 5, to get
732 = 5 x 146 + 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 732 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(732,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 339 > 1, we apply the division lemma to 339 and 1, to get
339 = 1 x 339 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 339 is 1
Notice that 1 = HCF(339,1) .
