Given numbers are 277, 780, 670, 913
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(277, 780) = 216060
GCD(277, 780) = ( 277 x 780 ) / 216060
= 277 / 780
= 277
Step2:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
Step3:
LCM(1, 913) = 913
GCD(1, 913) = ( 1 x 913 ) / 913
= 1 / 913
= 1
So, Greatest Common Divisor of 277, 780, 670, 913 is 1
