Given numbers are 642, 673, 993, 281
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 673) = 432066
GCD(642, 673) = ( 642 x 673 ) / 432066
= 642 / 673
= 642
Step2:
LCM(1, 993) = 993
GCD(1, 993) = ( 1 x 993 ) / 993
= 1 / 993
= 1
Step3:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
So, Greatest Common Divisor of 642, 673, 993, 281 is 1
