HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 523, 646, 155 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 923, 523, 646, 155 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 923, 523, 646, 155 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 923, 523, 646, 155 is 1.
HCF(923, 523, 646, 155) = 1
HCF of 923, 523, 646, 155 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 923, 523, 646, 155 is 1.
Highest Common Factor of 923,523,646,155 is 1
Step 1: Since 923 > 523, we apply the division lemma to 923 and 523, to get
923 = 523 x 1 + 400
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 400 and 523, to get
523 = 400 x 1 + 123
Step 3: We consider the new divisor 400 and the new remainder 123, and apply the division lemma to get
400 = 123 x 3 + 31
We consider the new divisor 123 and the new remainder 31,and apply the division lemma to get
123 = 31 x 3 + 30
We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get
31 = 30 x 1 + 1
We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 523 is 1
Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(123,31) = HCF(400,123) = HCF(523,400) = HCF(923,523) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 646 > 1, we apply the division lemma to 646 and 1, to get
646 = 1 x 646 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 646 is 1
Notice that 1 = HCF(646,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 155 > 1, we apply the division lemma to 155 and 1, to get
155 = 1 x 155 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 155 is 1
Notice that 1 = HCF(155,1) .
