Given numbers are 842, 846, 756, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 846) = 356166
GCD(842, 846) = ( 842 x 846 ) / 356166
= 842 / 846
= 842
Step2:
LCM(2, 756) = 756
GCD(2, 756) = ( 2 x 756 ) / 756
= 2 / 756
= 2
Step3:
LCM(2, 147) = 294
GCD(2, 147) = ( 2 x 147 ) / 294
= 2 / 147
= 2
So, Greatest Common Divisor of 842, 846, 756, 147 is 1
