HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 907, 438, 441 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 861, 907, 438, 441 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 861, 907, 438, 441 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 861, 907, 438, 441 is 1.
HCF(861, 907, 438, 441) = 1
HCF of 861, 907, 438, 441 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 861, 907, 438, 441 is 1.
Highest Common Factor of 861,907,438,441 is 1
Step 1: Since 907 > 861, we apply the division lemma to 907 and 861, to get
907 = 861 x 1 + 46
Step 2: Since the reminder 861 ≠ 0, we apply division lemma to 46 and 861, to get
861 = 46 x 18 + 33
Step 3: We consider the new divisor 46 and the new remainder 33, and apply the division lemma to get
46 = 33 x 1 + 13
We consider the new divisor 33 and the new remainder 13,and apply the division lemma to get
33 = 13 x 2 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 861 and 907 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(33,13) = HCF(46,33) = HCF(861,46) = HCF(907,861) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 438 > 1, we apply the division lemma to 438 and 1, to get
438 = 1 x 438 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 438 is 1
Notice that 1 = HCF(438,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 441 > 1, we apply the division lemma to 441 and 1, to get
441 = 1 x 441 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 441 is 1
Notice that 1 = HCF(441,1) .
