HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 185, 319, 421, 860 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 185, 319, 421, 860 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 185, 319, 421, 860 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 185, 319, 421, 860 is 1.
HCF(185, 319, 421, 860) = 1
HCF of 185, 319, 421, 860 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 185, 319, 421, 860 is 1.
Highest Common Factor of 185,319,421,860 is 1
Step 1: Since 319 > 185, we apply the division lemma to 319 and 185, to get
319 = 185 x 1 + 134
Step 2: Since the reminder 185 ≠ 0, we apply division lemma to 134 and 185, to get
185 = 134 x 1 + 51
Step 3: We consider the new divisor 134 and the new remainder 51, and apply the division lemma to get
134 = 51 x 2 + 32
We consider the new divisor 51 and the new remainder 32,and apply the division lemma to get
51 = 32 x 1 + 19
We consider the new divisor 32 and the new remainder 19,and apply the division lemma to get
32 = 19 x 1 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 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 185 and 319 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(32,19) = HCF(51,32) = HCF(134,51) = HCF(185,134) = HCF(319,185) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 860 > 1, we apply the division lemma to 860 and 1, to get
860 = 1 x 860 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 860 is 1
Notice that 1 = HCF(860,1) .
