Given numbers are 642, 297, 293, 331
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 297) = 63558
GCD(642, 297) = ( 642 x 297 ) / 63558
= 642 / 297
= 642
Step2:
LCM(3, 293) = 879
GCD(3, 293) = ( 3 x 293 ) / 879
= 3 / 293
= 3
Step3:
LCM(1, 331) = 331
GCD(1, 331) = ( 1 x 331 ) / 331
= 1 / 331
= 1
So, Greatest Common Divisor of 642, 297, 293, 331 is 1
