Given numbers are 642, 151, 275, 227
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 151) = 96942
GCD(642, 151) = ( 642 x 151 ) / 96942
= 642 / 151
= 642
Step2:
LCM(1, 275) = 275
GCD(1, 275) = ( 1 x 275 ) / 275
= 1 / 275
= 1
Step3:
LCM(1, 227) = 227
GCD(1, 227) = ( 1 x 227 ) / 227
= 1 / 227
= 1
So, Greatest Common Divisor of 642, 151, 275, 227 is 1
