Given numbers are 153, 578, 856, 970

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

Apply this formula for all numbers.

Step1:

LCM(153, 578) = 5202

GCD(153, 578) = ( 153 x 578 ) / 5202

= 153 / 578

= 153

Step2:

LCM(17, 856) = 14552

GCD(17, 856) = ( 17 x 856 ) / 14552

= 17 / 856

= 17

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 153, 578, 856, 970 is 1
