Given numbers are 780, 131, 308, 316
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 131) = 102180
GCD(780, 131) = ( 780 x 131 ) / 102180
= 780 / 131
= 780
Step2:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
Step3:
LCM(1, 316) = 316
GCD(1, 316) = ( 1 x 316 ) / 316
= 1 / 316
= 1
So, Greatest Common Divisor of 780, 131, 308, 316 is 1
