Given numbers are 670, 740, 858, 642

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

Apply this formula for all numbers.

Step1:

LCM(670, 740) = 49580

GCD(670, 740) = ( 670 x 740 ) / 49580

= 670 / 740

= 670

Step2:

LCM(10, 858) = 4290

GCD(10, 858) = ( 10 x 858 ) / 4290

= 10 / 858

= 10

Step3:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

So, Greatest Common Divisor of 670, 740, 858, 642 is 2
