HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 730, 754, 398 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 730, 754, 398 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 942, 730, 754, 398 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 942, 730, 754, 398 is 2.
HCF(942, 730, 754, 398) = 2
HCF of 942, 730, 754, 398 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 730, 754, 398 is 2.
Highest Common Factor of 942,730,754,398 is 2
Step 1: Since 942 > 730, we apply the division lemma to 942 and 730, to get
942 = 730 x 1 + 212
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 212 and 730, to get
730 = 212 x 3 + 94
Step 3: We consider the new divisor 212 and the new remainder 94, and apply the division lemma to get
212 = 94 x 2 + 24
We consider the new divisor 94 and the new remainder 24,and apply the division lemma to get
94 = 24 x 3 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 942 and 730 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(94,24) = HCF(212,94) = HCF(730,212) = HCF(942,730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 754 > 2, we apply the division lemma to 754 and 2, to get
754 = 2 x 377 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 754 is 2
Notice that 2 = HCF(754,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 2, we apply the division lemma to 398 and 2, to get
398 = 2 x 199 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 398 is 2
Notice that 2 = HCF(398,2) .
