Given numbers are 770, 947, 197, 479
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 947) = 729190
GCD(770, 947) = ( 770 x 947 ) / 729190
= 770 / 947
= 770
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
So, Greatest Common Divisor of 770, 947, 197, 479 is 1
