Given numbers are 105, 378, 645, 799
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 378) = 1890
GCD(105, 378) = ( 105 x 378 ) / 1890
= 105 / 378
= 105
Step2:
LCM(21, 645) = 4515
GCD(21, 645) = ( 21 x 645 ) / 4515
= 21 / 645
= 21
Step3:
LCM(3, 799) = 2397
GCD(3, 799) = ( 3 x 799 ) / 2397
= 3 / 799
= 3
So, Greatest Common Divisor of 105, 378, 645, 799 is 1
