Given numbers are 159, 642, 643, 962
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 642) = 34026
GCD(159, 642) = ( 159 x 642 ) / 34026
= 159 / 642
= 159
Step2:
LCM(3, 643) = 1929
GCD(3, 643) = ( 3 x 643 ) / 1929
= 3 / 643
= 3
Step3:
LCM(1, 962) = 962
GCD(1, 962) = ( 1 x 962 ) / 962
= 1 / 962
= 1
So, Greatest Common Divisor of 159, 642, 643, 962 is 1
