Given numbers are 642, 179, 753, 411
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 179) = 114918
GCD(642, 179) = ( 642 x 179 ) / 114918
= 642 / 179
= 642
Step2:
LCM(1, 753) = 753
GCD(1, 753) = ( 1 x 753 ) / 753
= 1 / 753
= 1
Step3:
LCM(1, 411) = 411
GCD(1, 411) = ( 1 x 411 ) / 411
= 1 / 411
= 1
So, Greatest Common Divisor of 642, 179, 753, 411 is 1
