HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 865, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 556, 865, 974 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 556, 865, 974 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 556, 865, 974 is 1.
HCF(556, 865, 974) = 1
HCF of 556, 865, 974 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 556, 865, 974 is 1.
Highest Common Factor of 556,865,974 is 1
Step 1: Since 865 > 556, we apply the division lemma to 865 and 556, to get
865 = 556 x 1 + 309
Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 309 and 556, to get
556 = 309 x 1 + 247
Step 3: We consider the new divisor 309 and the new remainder 247, and apply the division lemma to get
309 = 247 x 1 + 62
We consider the new divisor 247 and the new remainder 62,and apply the division lemma to get
247 = 62 x 3 + 61
We consider the new divisor 62 and the new remainder 61,and apply the division lemma to get
62 = 61 x 1 + 1
We consider the new divisor 61 and the new remainder 1,and apply the division lemma to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 556 and 865 is 1
Notice that 1 = HCF(61,1) = HCF(62,61) = HCF(247,62) = HCF(309,247) = HCF(556,309) = HCF(865,556) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 974 > 1, we apply the division lemma to 974 and 1, to get
974 = 1 x 974 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 974 is 1
Notice that 1 = HCF(974,1) .
