HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 677, 77, 844 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 677, 77, 844 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 870, 677, 77, 844 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 870, 677, 77, 844 is 1.
HCF(870, 677, 77, 844) = 1
HCF of 870, 677, 77, 844 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 677, 77, 844 is 1.
Highest Common Factor of 870,677,77,844 is 1
Step 1: Since 870 > 677, we apply the division lemma to 870 and 677, to get
870 = 677 x 1 + 193
Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 193 and 677, to get
677 = 193 x 3 + 98
Step 3: We consider the new divisor 193 and the new remainder 98, and apply the division lemma to get
193 = 98 x 1 + 95
We consider the new divisor 98 and the new remainder 95,and apply the division lemma to get
98 = 95 x 1 + 3
We consider the new divisor 95 and the new remainder 3,and apply the division lemma to get
95 = 3 x 31 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 870 and 677 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(95,3) = HCF(98,95) = HCF(193,98) = HCF(677,193) = HCF(870,677) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 844 > 1, we apply the division lemma to 844 and 1, to get
844 = 1 x 844 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 844 is 1
Notice that 1 = HCF(844,1) .
