GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 913) = 201773
GCD(221, 913) = ( 221 x 913 ) / 201773
= 221 / 913
= 221
Step2:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 221, 913, 459, 715 is 1
