Given numbers are 970, 620, 427, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 620) = 60140
GCD(970, 620) = ( 970 x 620 ) / 60140
= 970 / 620
= 970
Step2:
LCM(10, 427) = 4270
GCD(10, 427) = ( 10 x 427 ) / 4270
= 10 / 427
= 10
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 970, 620, 427, 770 is 1
