Given numbers are 645, 106, 476, 347
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 106) = 68370
GCD(645, 106) = ( 645 x 106 ) / 68370
= 645 / 106
= 645
Step2:
LCM(1, 476) = 476
GCD(1, 476) = ( 1 x 476 ) / 476
= 1 / 476
= 1
Step3:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
So, Greatest Common Divisor of 645, 106, 476, 347 is 1
