HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 839, 991, 651, 69 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 839, 991, 651, 69 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 839, 991, 651, 69 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 839, 991, 651, 69 is 1.
HCF(839, 991, 651, 69) = 1
HCF of 839, 991, 651, 69 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 839, 991, 651, 69 is 1.
Highest Common Factor of 839,991,651,69 is 1
Step 1: Since 991 > 839, we apply the division lemma to 991 and 839, to get
991 = 839 x 1 + 152
Step 2: Since the reminder 839 ≠ 0, we apply division lemma to 152 and 839, to get
839 = 152 x 5 + 79
Step 3: We consider the new divisor 152 and the new remainder 79, and apply the division lemma to get
152 = 79 x 1 + 73
We consider the new divisor 79 and the new remainder 73,and apply the division lemma to get
79 = 73 x 1 + 6
We consider the new divisor 73 and the new remainder 6,and apply the division lemma to get
73 = 6 x 12 + 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 839 and 991 is 1
Notice that 1 = HCF(6,1) = HCF(73,6) = HCF(79,73) = HCF(152,79) = HCF(839,152) = HCF(991,839) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get
651 = 1 x 651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1
Notice that 1 = HCF(651,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1
Notice that 1 = HCF(69,1) .
