HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 563, 156 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 563, 156 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 977, 563, 156 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 977, 563, 156 is 1.
HCF(977, 563, 156) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 977, 563, 156 is 1.
Step 1: Since 977 > 563, we apply the division lemma to 977 and 563, to get
977 = 563 x 1 + 414
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 414 and 563, to get
563 = 414 x 1 + 149
Step 3: We consider the new divisor 414 and the new remainder 149, and apply the division lemma to get
414 = 149 x 2 + 116
We consider the new divisor 149 and the new remainder 116,and apply the division lemma to get
149 = 116 x 1 + 33
We consider the new divisor 116 and the new remainder 33,and apply the division lemma to get
116 = 33 x 3 + 17
We consider the new divisor 33 and the new remainder 17,and apply the division lemma to get
33 = 17 x 1 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 563 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(33,17) = HCF(116,33) = HCF(149,116) = HCF(414,149) = HCF(563,414) = HCF(977,563) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 1, we apply the division lemma to 156 and 1, to get
156 = 1 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 156 is 1
Notice that 1 = HCF(156,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
