HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 628, 445, 924 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 871, 628, 445, 924 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 871, 628, 445, 924 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 871, 628, 445, 924 is 1.
HCF(871, 628, 445, 924) = 1
HCF of 871, 628, 445, 924 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 871, 628, 445, 924 is 1.
Highest Common Factor of 871,628,445,924 is 1
Step 1: Since 871 > 628, we apply the division lemma to 871 and 628, to get
871 = 628 x 1 + 243
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 243 and 628, to get
628 = 243 x 2 + 142
Step 3: We consider the new divisor 243 and the new remainder 142, and apply the division lemma to get
243 = 142 x 1 + 101
We consider the new divisor 142 and the new remainder 101,and apply the division lemma to get
142 = 101 x 1 + 41
We consider the new divisor 101 and the new remainder 41,and apply the division lemma to get
101 = 41 x 2 + 19
We consider the new divisor 41 and the new remainder 19,and apply the division lemma to get
41 = 19 x 2 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 871 and 628 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(41,19) = HCF(101,41) = HCF(142,101) = HCF(243,142) = HCF(628,243) = HCF(871,628) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 445 > 1, we apply the division lemma to 445 and 1, to get
445 = 1 x 445 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 445 is 1
Notice that 1 = HCF(445,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 924 > 1, we apply the division lemma to 924 and 1, to get
924 = 1 x 924 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 924 is 1
Notice that 1 = HCF(924,1) .
