HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 915, 398, 934 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 915, 398, 934 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, 398, 934 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, 398, 934 is 1.
HCF(655, 915, 398, 934) = 1
HCF of 655, 915, 398, 934 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, 398, 934 is 1.
Highest Common Factor of 655,915,398,934 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 398 > 5, we apply the division lemma to 398 and 5, to get
398 = 5 x 79 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
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 398 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(398,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 934 > 1, we apply the division lemma to 934 and 1, to get
934 = 1 x 934 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 934 is 1
Notice that 1 = HCF(934,1) .
