Given numbers are 621, 298, 411, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 298) = 185058
GCD(621, 298) = ( 621 x 298 ) / 185058
= 621 / 298
= 621
Step2:
LCM(1, 411) = 411
GCD(1, 411) = ( 1 x 411 ) / 411
= 1 / 411
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 621, 298, 411, 641 is 1
