Given numbers are 642, 181, 989, 535

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

Apply this formula for all numbers.

Step1:

LCM(642, 181) = 116202

GCD(642, 181) = ( 642 x 181 ) / 116202

= 642 / 181

= 642

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

So, Greatest Common Divisor of 642, 181, 989, 535 is 1
