HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 730, 506 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 456, 730, 506 is 2 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 456, 730, 506 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 456, 730, 506 is 2.
HCF(456, 730, 506) = 2
HCF of 456, 730, 506 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 456, 730, 506 is 2.
Highest Common Factor of 456,730,506 is 2
Step 1: Since 730 > 456, we apply the division lemma to 730 and 456, to get
730 = 456 x 1 + 274
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 274 and 456, to get
456 = 274 x 1 + 182
Step 3: We consider the new divisor 274 and the new remainder 182, and apply the division lemma to get
274 = 182 x 1 + 92
We consider the new divisor 182 and the new remainder 92,and apply the division lemma to get
182 = 92 x 1 + 90
We consider the new divisor 92 and the new remainder 90,and apply the division lemma to get
92 = 90 x 1 + 2
We consider the new divisor 90 and the new remainder 2,and apply the division lemma to get
90 = 2 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 456 and 730 is 2
Notice that 2 = HCF(90,2) = HCF(92,90) = HCF(182,92) = HCF(274,182) = HCF(456,274) = HCF(730,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 506 > 2, we apply the division lemma to 506 and 2, to get
506 = 2 x 253 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 506 is 2
Notice that 2 = HCF(506,2) .
