Given numbers are 970, 475, 355, 642

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

Apply this formula for all numbers.

Step1:

LCM(970, 475) = 92150

GCD(970, 475) = ( 970 x 475 ) / 92150

= 970 / 475

= 970

Step2:

LCM(5, 355) = 355

GCD(5, 355) = ( 5 x 355 ) / 355

= 5 / 355

= 5

Step3:

LCM(5, 642) = 3210

GCD(5, 642) = ( 5 x 642 ) / 3210

= 5 / 642

= 5

So, Greatest Common Divisor of 970, 475, 355, 642 is 1
