Given numbers are 357, 617, 170, 190
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 617) = 220269
GCD(357, 617) = ( 357 x 617 ) / 220269
= 357 / 617
= 357
Step2:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
Step3:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
So, Greatest Common Divisor of 357, 617, 170, 190 is 1
