HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 445, 707, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 445, 707, 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 388, 445, 707, 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 388, 445, 707, 818 is 1.
HCF(388, 445, 707, 818) = 1
HCF of 388, 445, 707, 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 388, 445, 707, 818 is 1.
Highest Common Factor of 388,445,707,818 is 1
Step 1: Since 445 > 388, we apply the division lemma to 445 and 388, to get
445 = 388 x 1 + 57
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 57 and 388, to get
388 = 57 x 6 + 46
Step 3: We consider the new divisor 57 and the new remainder 46, and apply the division lemma to get
57 = 46 x 1 + 11
We consider the new divisor 46 and the new remainder 11,and apply the division lemma to get
46 = 11 x 4 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 388 and 445 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(46,11) = HCF(57,46) = HCF(388,57) = HCF(445,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 707 > 1, we apply the division lemma to 707 and 1, to get
707 = 1 x 707 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 707 is 1
Notice that 1 = HCF(707,1) .
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) .
