Given numbers are 642, 167, 125, 259
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 167) = 107214
GCD(642, 167) = ( 642 x 167 ) / 107214
= 642 / 167
= 642
Step2:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
Step3:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
So, Greatest Common Divisor of 642, 167, 125, 259 is 1
