Given numbers are 201, 715, 889, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(201, 715) = 143715
GCD(201, 715) = ( 201 x 715 ) / 143715
= 201 / 715
= 201
Step2:
LCM(1, 889) = 889
GCD(1, 889) = ( 1 x 889 ) / 889
= 1 / 889
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 201, 715, 889, 781 is 1
