Given numbers are 621, 519, 153, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 519) = 107433
GCD(621, 519) = ( 621 x 519 ) / 107433
= 621 / 519
= 621
Step2:
LCM(3, 153) = 153
GCD(3, 153) = ( 3 x 153 ) / 153
= 3 / 153
= 3
Step3:
LCM(3, 122) = 366
GCD(3, 122) = ( 3 x 122 ) / 366
= 3 / 122
= 3
So, Greatest Common Divisor of 621, 519, 153, 122 is 1
