Given numbers are 642, 714, 222, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 714) = 76398
GCD(642, 714) = ( 642 x 714 ) / 76398
= 642 / 714
= 642
Step2:
LCM(6, 222) = 222
GCD(6, 222) = ( 6 x 222 ) / 222
= 6 / 222
= 6
Step3:
LCM(6, 385) = 2310
GCD(6, 385) = ( 6 x 385 ) / 2310
= 6 / 385
= 6
So, Greatest Common Divisor of 642, 714, 222, 385 is 1
