HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 167, 977, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 167, 977, 780 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 167, 977, 780 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 167, 977, 780 is 1.
HCF(167, 977, 780) = 1
HCF of 167, 977, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 167, 977, 780 is 1.
Highest Common Factor of 167,977,780 is 1
Step 1: Since 977 > 167, we apply the division lemma to 977 and 167, to get
977 = 167 x 5 + 142
Step 2: Since the reminder 167 ≠ 0, we apply division lemma to 142 and 167, to get
167 = 142 x 1 + 25
Step 3: We consider the new divisor 142 and the new remainder 25, and apply the division lemma to get
142 = 25 x 5 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 167 and 977 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(142,25) = HCF(167,142) = HCF(977,167) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get
780 = 1 x 780 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1
Notice that 1 = HCF(780,1) .
