Given numbers are 40, 10, 70, 58

The list of prime factors of all numbers are

Prime factors of 40 are 2 x 2 x 2 x 5

Prime factors of 10 are 2 x 5

Prime factors of 70 are 2 x 5 x 7

Prime factors of 58 are 2 x 29

The highest common occurrence is 2¹

Therefore, GCD of 40, 10, 70, 58 is 2.

Given numbers are 40, 10, 70, 58

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(40, 10) = 40

GCD(40, 10) = ( 40 x 10 ) / 40

= 40 / 10

= 40

Step2:

LCM(10, 70) = 70

GCD(10, 70) = ( 10 x 70 ) / 70

= 10 / 70

= 10

Step3:

LCM(10, 58) = 290

GCD(10, 58) = ( 10 x 58 ) / 290

= 10 / 58

= 10

So, Greatest Common Divisor of 40, 10, 70, 58 is 2
