HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 623, 49, 913 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 623, 49, 913 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, 623, 49, 913 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, 623, 49, 913 is 1.
HCF(655, 623, 49, 913) = 1
HCF of 655, 623, 49, 913 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, 623, 49, 913 is 1.
Highest Common Factor of 655,623,49,913 is 1
Step 1: Since 655 > 623, we apply the division lemma to 655 and 623, to get
655 = 623 x 1 + 32
Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 32 and 623, to get
623 = 32 x 19 + 15
Step 3: We consider the new divisor 32 and the new remainder 15, and apply the division lemma to get
32 = 15 x 2 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 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 655 and 623 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(32,15) = HCF(623,32) = HCF(655,623) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 913 > 1, we apply the division lemma to 913 and 1, to get
913 = 1 x 913 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 913 is 1
Notice that 1 = HCF(913,1) .
