Given numbers are 643, 305, 242, 562
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 305) = 196115
GCD(643, 305) = ( 643 x 305 ) / 196115
= 643 / 305
= 643
Step2:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
Step3:
LCM(1, 562) = 562
GCD(1, 562) = ( 1 x 562 ) / 562
= 1 / 562
= 1
So, Greatest Common Divisor of 643, 305, 242, 562 is 1
