Given numbers are 970, 655, 651, 618
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 655) = 127070
GCD(970, 655) = ( 970 x 655 ) / 127070
= 970 / 655
= 970
Step2:
LCM(5, 651) = 3255
GCD(5, 651) = ( 5 x 651 ) / 3255
= 5 / 651
= 5
Step3:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
So, Greatest Common Divisor of 970, 655, 651, 618 is 1
