Given numbers are 639, 801, 393, 542

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

Apply this formula for all numbers.

Step1:

LCM(639, 801) = 56871

GCD(639, 801) = ( 639 x 801 ) / 56871

= 639 / 801

= 639

Step2:

LCM(9, 393) = 1179

GCD(9, 393) = ( 9 x 393 ) / 1179

= 9 / 393

= 9

Step3:

LCM(3, 542) = 1626

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

= 3 / 542

= 3

So, Greatest Common Divisor of 639, 801, 393, 542 is 1
