Given numbers are 107, 642, 178, 465
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(107, 642) = 642
GCD(107, 642) = ( 107 x 642 ) / 642
= 107 / 642
= 107
Step2:
LCM(107, 178) = 19046
GCD(107, 178) = ( 107 x 178 ) / 19046
= 107 / 178
= 107
Step3:
LCM(1, 465) = 465
GCD(1, 465) = ( 1 x 465 ) / 465
= 1 / 465
= 1
So, Greatest Common Divisor of 107, 642, 178, 465 is 1
