HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 994, 956, 216 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 994, 956, 216 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 402, 994, 956, 216 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 402, 994, 956, 216 is 2.
HCF(402, 994, 956, 216) = 2
HCF of 402, 994, 956, 216 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 402, 994, 956, 216 is 2.
Highest Common Factor of 402,994,956,216 is 2
Step 1: Since 994 > 402, we apply the division lemma to 994 and 402, to get
994 = 402 x 2 + 190
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 190 and 402, to get
402 = 190 x 2 + 22
Step 3: We consider the new divisor 190 and the new remainder 22, and apply the division lemma to get
190 = 22 x 8 + 14
We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get
22 = 14 x 1 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 402 and 994 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(190,22) = HCF(402,190) = HCF(994,402) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 956 > 2, we apply the division lemma to 956 and 2, to get
956 = 2 x 478 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 956 is 2
Notice that 2 = HCF(956,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 216 > 2, we apply the division lemma to 216 and 2, to get
216 = 2 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 216 is 2
Notice that 2 = HCF(216,2) .
