Given numbers are 972, 620, 166, 278

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

Apply this formula for all numbers.

Step1:

LCM(972, 620) = 150660

GCD(972, 620) = ( 972 x 620 ) / 150660

= 972 / 620

= 972

Step2:

LCM(4, 166) = 332

GCD(4, 166) = ( 4 x 166 ) / 332

= 4 / 166

= 4

Step3:

LCM(2, 278) = 278

GCD(2, 278) = ( 2 x 278 ) / 278

= 2 / 278

= 2

So, Greatest Common Divisor of 972, 620, 166, 278 is 2
