HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 745, 930, 667 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 745, 930, 667 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 309, 745, 930, 667 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 309, 745, 930, 667 is 1.
HCF(309, 745, 930, 667) = 1
HCF of 309, 745, 930, 667 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 745, 930, 667 is 1.
Highest Common Factor of 309,745,930,667 is 1
Step 1: Since 745 > 309, we apply the division lemma to 745 and 309, to get
745 = 309 x 2 + 127
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 127 and 309, to get
309 = 127 x 2 + 55
Step 3: We consider the new divisor 127 and the new remainder 55, and apply the division lemma to get
127 = 55 x 2 + 17
We consider the new divisor 55 and the new remainder 17,and apply the division lemma to get
55 = 17 x 3 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 309 and 745 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(127,55) = HCF(309,127) = HCF(745,309) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 1, we apply the division lemma to 930 and 1, to get
930 = 1 x 930 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 930 is 1
Notice that 1 = HCF(930,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 667 > 1, we apply the division lemma to 667 and 1, to get
667 = 1 x 667 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 667 is 1
Notice that 1 = HCF(667,1) .
