HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 372, 691, 49 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 372, 691, 49 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 980, 372, 691, 49 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 980, 372, 691, 49 is 1.
HCF(980, 372, 691, 49) = 1
HCF of 980, 372, 691, 49 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 372, 691, 49 is 1.
Highest Common Factor of 980,372,691,49 is 1
Step 1: Since 980 > 372, we apply the division lemma to 980 and 372, to get
980 = 372 x 2 + 236
Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 236 and 372, to get
372 = 236 x 1 + 136
Step 3: We consider the new divisor 236 and the new remainder 136, and apply the division lemma to get
236 = 136 x 1 + 100
We consider the new divisor 136 and the new remainder 100,and apply the division lemma to get
136 = 100 x 1 + 36
We consider the new divisor 100 and the new remainder 36,and apply the division lemma to get
100 = 36 x 2 + 28
We consider the new divisor 36 and the new remainder 28,and apply the division lemma to get
36 = 28 x 1 + 8
We consider the new divisor 28 and the new remainder 8,and apply the division lemma to get
28 = 8 x 3 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 980 and 372 is 4
Notice that 4 = HCF(8,4) = HCF(28,8) = HCF(36,28) = HCF(100,36) = HCF(136,100) = HCF(236,136) = HCF(372,236) = HCF(980,372) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 691 > 4, we apply the division lemma to 691 and 4, to get
691 = 4 x 172 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 691 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(691,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
