HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 836, 380, 644, 605 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 836, 380, 644, 605 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 836, 380, 644, 605 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 836, 380, 644, 605 is 1.
HCF(836, 380, 644, 605) = 1
HCF of 836, 380, 644, 605 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 836, 380, 644, 605 is 1.
Highest Common Factor of 836,380,644,605 is 1
Step 1: Since 836 > 380, we apply the division lemma to 836 and 380, to get
836 = 380 x 2 + 76
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 76 and 380, to get
380 = 76 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 76, the HCF of 836 and 380 is 76
Notice that 76 = HCF(380,76) = HCF(836,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 644 > 76, we apply the division lemma to 644 and 76, to get
644 = 76 x 8 + 36
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 36 and 76, to get
76 = 36 x 2 + 4
Step 3: We consider the new divisor 36 and the new remainder 4, and apply the division lemma to get
36 = 4 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 76 and 644 is 4
Notice that 4 = HCF(36,4) = HCF(76,36) = HCF(644,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 605 > 4, we apply the division lemma to 605 and 4, to get
605 = 4 x 151 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 605 is 1
Notice that 1 = HCF(4,1) = HCF(605,4) .
