Given numbers are 861, 657, 542, 752

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

Apply this formula for all numbers.

Step1:

LCM(861, 657) = 188559

GCD(861, 657) = ( 861 x 657 ) / 188559

= 861 / 657

= 861

Step2:

LCM(3, 542) = 1626

GCD(3, 542) = ( 3 x 542 ) / 1626

= 3 / 542

= 3

Step3:

LCM(1, 752) = 752

GCD(1, 752) = ( 1 x 752 ) / 752

= 1 / 752

= 1

So, Greatest Common Divisor of 861, 657, 542, 752 is 1
