Given numbers are 645, 105, 828, 925
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 105) = 4515
GCD(645, 105) = ( 645 x 105 ) / 4515
= 645 / 105
= 645
Step2:
LCM(15, 828) = 4140
GCD(15, 828) = ( 15 x 828 ) / 4140
= 15 / 828
= 15
Step3:
LCM(3, 925) = 2775
GCD(3, 925) = ( 3 x 925 ) / 2775
= 3 / 925
= 3
So, Greatest Common Divisor of 645, 105, 828, 925 is 1
