HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 669, 233, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 669, 233, 818 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 770, 669, 233, 818 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 770, 669, 233, 818 is 1.
HCF(770, 669, 233, 818) = 1
HCF of 770, 669, 233, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 669, 233, 818 is 1.
Highest Common Factor of 770,669,233,818 is 1
Step 1: Since 770 > 669, we apply the division lemma to 770 and 669, to get
770 = 669 x 1 + 101
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 101 and 669, to get
669 = 101 x 6 + 63
Step 3: We consider the new divisor 101 and the new remainder 63, and apply the division lemma to get
101 = 63 x 1 + 38
We consider the new divisor 63 and the new remainder 38,and apply the division lemma to get
63 = 38 x 1 + 25
We consider the new divisor 38 and the new remainder 25,and apply the division lemma to get
38 = 25 x 1 + 13
We consider the new divisor 25 and the new remainder 13,and apply the division lemma to get
25 = 13 x 1 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 770 and 669 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(38,25) = HCF(63,38) = HCF(101,63) = HCF(669,101) = HCF(770,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 233 > 1, we apply the division lemma to 233 and 1, to get
233 = 1 x 233 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 233 is 1
Notice that 1 = HCF(233,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 1, we apply the division lemma to 818 and 1, to get
818 = 1 x 818 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 818 is 1
Notice that 1 = HCF(818,1) .
