Given numbers are 670, 205, 145, 653

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

Apply this formula for all numbers.

Step1:

LCM(670, 205) = 27470

GCD(670, 205) = ( 670 x 205 ) / 27470

= 670 / 205

= 670

Step2:

LCM(5, 145) = 145

GCD(5, 145) = ( 5 x 145 ) / 145

= 5 / 145

= 5

Step3:

LCM(5, 653) = 3265

GCD(5, 653) = ( 5 x 653 ) / 3265

= 5 / 653

= 5

So, Greatest Common Divisor of 670, 205, 145, 653 is 1
