HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 360, 516, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 360, 516, 421 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 360, 516, 421 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 360, 516, 421 is 1.
HCF(360, 516, 421) = 1
HCF of 360, 516, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 360, 516, 421 is 1.
Highest Common Factor of 360,516,421 is 1
Step 1: Since 516 > 360, we apply the division lemma to 516 and 360, to get
516 = 360 x 1 + 156
Step 2: Since the reminder 360 ≠ 0, we apply division lemma to 156 and 360, to get
360 = 156 x 2 + 48
Step 3: We consider the new divisor 156 and the new remainder 48, and apply the division lemma to get
156 = 48 x 3 + 12
We consider the new divisor 48 and the new remainder 12, and apply the division lemma to get
48 = 12 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 360 and 516 is 12
Notice that 12 = HCF(48,12) = HCF(156,48) = HCF(360,156) = HCF(516,360) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 12, we apply the division lemma to 421 and 12, to get
421 = 12 x 35 + 1
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 1 and 12, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 421 is 1
Notice that 1 = HCF(12,1) = HCF(421,12) .
