Given numbers are 679, 972, 653, 399

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

Apply this formula for all numbers.

Step1:

LCM(679, 972) = 659988

GCD(679, 972) = ( 679 x 972 ) / 659988

= 679 / 972

= 679

Step2:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 679, 972, 653, 399 is 1
